My neighbor has a "mowing crew" mow for them. Its actually two kids with toys, one is the daughters boyfriend. Anyway, last year they started using a riding tractor to mow, (city lot approx 100x100, large house, driveway, etc.) and started blowing grass in my yard. I went to talk to the kid and he started off about me not having to be a dick about it, just ask nice. So I talked to the owner, they said no problem, sorry, wont happen again. Well, here we are again, now they have a ???? brand walk behind, approx 42", and made a huge mess with it. Problem is, no one ever seems to be home, and these kids always seem to mow while Im not here. Not that I should EVER have to say a word. I take a lot of pride in my yard and the way it looks, and this crap pisses me off. Especially since I already talked to them once about it. I know they dont have insurance or anything, and probably just started last year, but seems to me I should be able to do something about it.......Any ideas?
