This is slightly different from what you are looking at, but is some ways appropriate. Using Google Earth you should be able to locate the position of the tree you planted with or with out GPS. Find the general area where the tree was planted and zoom into the area and find the nearly exact the location where you planted the tree. You can increase the accuracy of the position by measuring from two hard object that can be seen in Google Earth to the tree, then transfer those measurements to the Google Earth using the measuring function in Google earth. You can measure things in Google earth to the nearest foot.. Once you locate the trees you planted in Google Earth place a Placemark at the site of each tree. In the Placemark description you can place all of the statistics about the tree. While I have never seen, you can back up all of this information, and transfer it to other computers with Google Earth. These two files contain that information myplaces.backup.kml and myplaces.kml Copy them to the folder you want to use as a back up or copy them in the same Google directory on the other computer. If you install Google Earth you will be over writing the ones created on installation. In Window 8.1 they are located in C:\Users\account \AppData\LocalLow\Google\GoogleEarth Account is the name of the user account. If you have an earlier version of Windows they are in the Application data. Or you can search for them use the above file name. I transferred the information to my Windows 8.1 computer from and Windows XP computer using this technique. I have used this exact procedure to locate ancestors graves to archive the location. I hope this proves to be useful. This post was edited by knuttle on Mon, Nov 18, 13 at 13:02

I suggest buying the Honda unit. They are very friendly and much easier to use with their larger displays and such than a portable unit. They also can't be stolen since they are part of the car (not easily anyway). If you do want to buy a portable unit, Garmen units are superb from ease of use. Like the Honda unit, they are pricier than the competition but work quite well (I have two).

GPS is just as good as the person who sets it. heehee. We just came back from a trip that took us 2 hrs more then it should have because i put the wrong address in GPS. We still love our GPS. It was great to find our way back even after my mistake. Hurry for GPS.

let me preface this by saying i am an expert in semi logistics, i route & ship more than $10 million worth of landscape plant materials ea yr, from south VA to the TX border, for the last 9 yrs. he CAN NOT use one that is a regular GPS, it MUST be only a model for semi trucks. he needs to check out the truck stops(or their websites), they sell the best ones and for the best prices. be prepared to spend lot more than any regular models, atleast $300-400. truck models have settings that come up w/ routes based on what roads, bridges and overpasses semi's can drive. using a car model GPS will soon get you a tix that will cost more than a weeks pay and add points to your license and make it difficult for the employer to get insurance coverage for you plus you will not be able to easily get jobs w/ points on your record. we do not hire drivers that have points on their record or have ever had any tix other than DOT trailer issues. i once had a lost driver get himself stuck on a steep declining residential road in Birmingham AL because he used a Garmin for cars. that tow cost $850, he was gone the next week. congrats to your son, i hope he really loves driving LOL! i used to have several drivers who had been w/ us for many many yrs but they all left over the last yr to drive for the same cross country hauler making $2000 a week and home on weekends too. there is $$ to make in that industry and it's only growing, gas prices will not affect it alot as people need their goods no matter what the cost. i would like to also suggest he get a very good bluetooth headset, not the cheapie kind everday people use, it needs to be one that wraps around the top of the head and has earphones w/ a boom speaker. my veteran drivers all have that one (all got at pilot truck stops i think) and it makes a tremendous difference in my ability to hear them w/ their windows open (they won't change that LOL) and in them being able to hear my loud mouth LOL. again congrats! if he's ever looking for something based in central fl or wants names of cross country hauling jobs send me an email! ~ liz
