I was with my dad in a Pizza place parking lot, we were in the Yukon waiting for my mom to come out. Anyway this explorer parks next to us. 16 year old or so kid gets out and hits the back passenger door pretty hard. My dad looked over about to get out but didnt. When the people were gone, he got out pulled his leatherman and put a 6ft line down the side. And if that wasn't bad enough he cut two valve stems. Not really propper to piss off a guy in a brand new Yukon XL
