I was just asked to take care of some common property in one of the communities I work in. I appears to be about 2 acres of undergrowth (vines, grasses, weeds, etc). Another contractor in the community had been scheduled to do it, but he hasn't shown yet. They asked me to do it, and since I do quite a bit of work in the community it's worth the good PR in addition to the $$. What do y'all recommend for one time kill.
