Hi guys...I found my car immediately when I was on the right floor! I just didn't remember I had not parked on the same floor as my friends. Both of our cars have antenna's in the windshield or I would put a huge round ball on the antenna with 'over here, stupid' printed in big black letters. I have tried to get into other peoples vehicles more times that I can count. And the sad thing is, half the time they don't even look like my car!
