I went to the OU/Texas game on 6 Oct 2007, parking was limited so I parked in a ladies yard. The lady said it was OK to park there if I wanted to pay $20. I paid her the $20 and went on to the game. I returned to my truck and found a parking ticket for $40. I just got another notice in the mail saying that payment is due by 19 Oct 2007. Does anyone have any advice. Thanks in advance.
