Here is the pic-

lol..wonder if if you're been tagged??? have they been out working? if not, wash it off...so glad we have stone driveway....

thinking about it, most of the time the utilities use spray paint...

If I were a child with chalk, I wouldn't necessarily write on my own driveway. I remember I used to "write" with these rocks we had that seemed to work like chalk, indiscriminately on the street itself, back when I was five or six. I wouldn't worry about it or think about it any more.

If it was a utility group of any sort, seems like they'd let you know what was happening. When they were looking at trimming trees in my neighborhood, they came by and left a leaflet on the door to say when. I was there and we discussed my trees at my time. I even had them cut one down completely. For free. This is in podunk Nashville, so I assume most places probably operate this way? Merely one opinion.

I don't think a utility worker would add the smiley face, just my 2 cents.

Door to door salespeople in my area "tag" driveways with chalk to communicate to their supervisor or the next salesperson the status of that home. There's probably one kind of mark to indicate an attempt was made but no one answered the door (so a salesperson can try again) and another kind of mark to indicate that contact with the homeowner was made. If you scrub it off, they'll ring your doorbell again since they'll think you haven't yet been approached for their so-very-wonderful product/services.

Jewelisfab- we don't get door to door back here. It is illegal. It is washed away now by my handy, dandy garden hose.

Had a long chat with the teen next door and there's been no chalking activity coming from their place. There's really no other kids close enough to want to do that there, so I will have to "chalk" it up to being a mystery.

A mystery? One of my favorite things about Geoffrey Rush in Shakespere in Love!He says, all movie long. "I dunno it's a mystery!"

Do you have a wifi router in your house? Do you have it secured with WPA2 and locked down?
called war driving.
There are people who drive around looking for wifi networks that are not secured so that they can get free wifi access and they will mark the driveway with chalk. That is one definite use of chalk on the driveway. I am told that homeless people and travelers also mark driveways of places that you can take shelter on the property or find food etc. There are also stories of dog nappers using that kind of chalk code.

And the scariest of all is burglars use it to mark the houses to hit next.

chalk marks for criminals

Wifi is protected cajun. Could be a burglar mark I guess, but I feel sorry for them if it is. This IS Texas:) ... and you know what I mean.

At the range, if I aim high I always catch the target in the groin.

we had a lot of fun chalking the side walk... my driveway is brick, not good for chalking.

further up we had a smiley face, and Just Kidding. :)

I know exactly what you mean! LOL

That would have been mine when I had the grands for the summer! Love it!

As soon as stops raining, I'm going to run out and chalk this on my driveway:

Wasn't that a UK article. So UK thieves won't visit you ;)

It reminds me of mark made by A) The Zodiac killer in the 70s or B) by someone else who ended up having to explain herself. Very different here!

Be on the lookout for someone wearing a raincoat, eating fish and chips, and driving on the wrong side of the road.

I wouldn't be concerned about it.

The hobos would not put a mark in an obvious place. It would be small, on a fencepost, on the underside of a mailbox, etc.

It makes sense that the wifi trollers, etc., would make a mark that looked like a kid did it so people wouldn't be alarmed and would be less likely to remove it. I never heard of them chalking like that, but it does make sense.

If it's stenciled spray paint and points to a similar stencil (not your house), usually something cute, it's drug dealers.

It looks like aimless doodling.

Warchalking uses specific symbols. This is definitely not warchalking.

I agree with Jemdandy. It's a harmless doodle. If it's pink like it appears on my monitor I would look for a princess, wearing a tiara, eating a popsicle. ;-)

A smiley wearing a hat is what it looks like to me, a child's idea of creative art.

My grandkids are chalk masters. Be wary of these kids. They'll mark up every sidewalk, porch and driveway they can find. They practice their art spring, summer and fall.

I invite my little neighbors to use chalk on our sidewalk and driveway! I've been spotted 'helping' decorate with chalk flowers.

Why would war drivers need to mark a house. Sometimes when we are out and about I take my tablet and use an app called Wi-Fi Finder just to see how many open networks I can find. First time I did it I was surprised at how many people don't secure their network. We usually drive by too fast to connect to any of them but I do see them.

Pooh Bear

The symbols used to mark a house are to designate how open the network is and how easily accessible despite encryption,firewalls etc. War driving/chalking goes beyond just looking for wide open networks purposefully left open. The marks may indicate levels of security measures in place. The marks may also indicate a closed network. Serious war drivers had/have the skills and equipment to break through encryption barriers.

I don't think war driving is very prevalent these days. Like you said, Pooh, open networks are on apps these days. Last time DS was asked to give a demo was back in 2008 or so.

Hi everyone- been out for a day and I saw all the new posts. The kids are super cute. I think I can eliminate some possibilities about who made the mark and as for why... who knows.

The area where this was marked is covered by security cams which are motion sensitive. They trigger better in daylight than at night, so if it was kids during the day, that would have triggered the cams. Street distance rarely comes up at night- something has to come closer to the cam. So, the mark was probably made at night by someone who saw our cam location (they have red infrared lights which are visible). I went back awhile on the footage and there are no daytime chalkers.

Still, like I said- I am in no way concerned about a break in where we are for a variety of reasons. Because of our elevation, safety gate, unusual garage door features and cams, there are a lot of easier targets around here. And like I said before, if they want to try, they are very likely to get a very inhospitable response.

Pretty sure you have been "tagged" and are now on the "terrorist watch list".

Some of the replies are pretty out there, though. LOL

Angelaid- lol. There's a lot that goes on in this old world we don't know about. At least the chalk mark was not as disturbing as the beach blowing up under that woman in Rhode Island a few days ago. They still don't know what sent her flying 10 feet into the air.
