The point is, CNN has a nifty little site that shows you how many labs are/were in your neck of the woods. You should probably learn where they are, too — once a building is used to create meth, it takes a lot of work to clean it up.
One of VAR’s bills on this year’s legislative agenda — one that is likely to pass — requires disclosure if a property was once used as a meth lab.
Some areas have it easier than others. Appomattox, for example, has a single former lab; I would hope it’s known locally as “the meth house.” Others — I’m looking at you, Smyth County — have a bit more going on. (30 labs? Really?)
