That happened to me this summer! I jacked it up on some newish asphalt on a hot day - I was SO PI$$ED!!! It was the one time I decided not to take my cellphone and for some reason nobody that stopped had one either. It didn't help that the store nearby wouldn't let me use their phone.

Anyway, everything was fine with my car - thank goodness because I had to go on a 2000 mile road trip the next day. I was just on my way home from getting a new set of tires too... ouch. I know have a floorjack in my trunk. Stupid jack.
