I remember a Member on Pelletheads had season tickets to the Cowboys right after they opened the new Texas Stadium. He was selling tickets for one game he had 4, I do not believe they were great seats, 2nd level closer to end zone. This was probably 8-10 years ago and he want $430 a ticket I believe. That is when I knew my in stadium professional sports days were probably over.
I know I took my uncle to a Dodger game in 2008, one of the owners of the Insurance company I was working for had season tickets. 1st base line, about 10 rows up and they were $125 each! Seems like a bargain now!
