I know what you are talking about Stocker. Last Year my main drain pipe from the front of the house to the street was backing up all because of a stupid tree, that the morons at the city had planted right above the pipes. It went through mine and the neighbors. So I called the city asking is it mine or their tree, and waited and waited for a response. I finally said screw them and drilled a hole through the trunk, chained it to my old dodge truck, and ripped that s.o.b. right out of the ground. After I had trenched it to that point so I could replace it that day. Then replaced it with all new abs instead of that crappy clay pipe they had in there. What a mess though, then today this crap.
