check out MSNBC undercover HOMEWRECKERS program. A very interesting look at low quality and crooked contracters. I watched through the eyes of a tree care company owner and how I do buisness. One pair of "tree climbers" got busted showing up for work unlicensed, uninsured, stoned and they even brought some pot with them. How would a task force like this impact your world? I deal with the guys who know nothing about tree work but still do it, guys who claim to know about tree work but don't and even some folks who appear legit (even certified!) but will do questionable work nonetheless. Watch it if you get the chance.
