Have had Season Tix to the Chicago Bulls for 21 years....Have been thru the great years MJ and the crappy years...Old stadium was better, and my seats are 5 rows of the floor behind the bench.
Season tickets to the Houston Texans for the past 3 years. It's awesome. You get to know the people around you, have "your" seats. If you can afford it, I definitely recommend it.
I got Patriots tix, was on the waiting list for 10 years before finally getting them. Usually go to 2 games a year, selling the rest, and break even or make a small profit including the 2 i go to.
