I don't piss people off. I don't have any enemies that I know of. I was thinking it could be some little punk kids who live across 9th ave. A while back they stole one of my little brother's friend's bikes right from our front porch. My dad saw them a day later and chased them down in this truck, maybe it is them getting revenge. My dad is out of town though. I tried giving it a good rub down with car soap and water but to no avail, it didn't come off.
