I don't have any particular fondness for rodents, but I just don't have the heart to kill an animal. For me "exclusion" is a much easier method. I just keep all my roses in gopher cages, and have no problems. But I do laugh when I see a ring of gopher mounds around a caged rose. On a related subject, I was going crazy with my son's cat who is a rat killing machine. There are weeks when I end up with 2 or 3 dead rats in the house, or patio. So, I came up with a new program called "Rats for Roses" Each time the cat brings me a dead rat, I bury it under one of my rose bushes. I have about 30 roses, so I just keep buring them , eventually all 30 roses end up with a nice little bonemeal/bloodmeal treat. By the time all 30 have been given a rat, the first rose is ready for another one. It's good for the roses, and it gives the little fellers a decnt burial.

Yes same as firefox 3----- no it will not replace IE6 you will just have an extra browser an that's good to have for trouble shooting like now. The only time IE6 is replaced is if you install another IE browser. Like IE7 OR IE8 So give it a shot nothing to loose and maybe things to gain.

The VAH hood has squirrel cage fans that also act as grease slingers. This type requires disassembly to some degree for cleaning. Mesh filter and baffle filter hoods require removal of the filters for cleaning. This is normally simpler to perform than cleaning squirrel cage motor assemblies. Baffles filter even when dirty; meshes must be cleaned to keep airflow up. No system removes all sizes of grease particles except intense UV systems not applicable here. Except for the VAH, all other configurations use fans for air movement only. Some have fans in the hood, some in-line with the ducting, and some on the roof. In-line and roof fans may be selected separately from the hood in many cases. Fans operating above (past) the filtering media should not require normal cleaning, but I wouldn't claim perpetual freedom. Fans with what one would call blades can have different configurations of blades depending on many factors that are probably outside the interest of most of us. The important factor is the "fan curve," or plot of flow rate versus the pressure difference across the fan. The more vertical the line is from the zero static pressure point, the more resistant the fan flow will be to pressure loss from duct friction, air turbulence in the baffles, flow past meshes, aerodynamic effects at duct transitions and hood aperture, etc. Best/Broan (and Wolf) can provide fan curves. Very likely Greenheck does for commercial units. I don't know of other manufacturers' habits. I would expect all residential fans to have monotonic fan curves; otherwise, there can be some setting/restriction that would cause the fan to hunt (cycle between two speeds). kas

I found it to be a huge time-waster for me personally, although I know many people for whom it just works. I was just talking to a friend last night who said she enjoys being able to keep up with her kids via Facebook, and I can totally understand that. I also enjoyed reconnecting with some folks from the past, but I can honestly say that out of the 249 friends I had "amassed", I really only cared to keep in touch with a handful of them with any regularity. I let those few know I was "leaving the pack", but made sure we exchanged email addresses so we can stay in touch. I doubt the rest even realize I'm not on Facebook anymore. Totally agree with you about not caring where everyone is, every moment of the day. Mary Smith just 'dropped the kids off at the pool'. (OK, so I don't know anybody who actually posted that, but some folks did come pretty darn close. Way, way, way TMI.) ;-)
