Heres a breakdown of the most expensive average ticket prices from a sports paper and web site:
Most expensive
Team Average price
Washington $81.89
Denver 77.41
Jacksonville 62.85
Pittsburgh 62.03
Tennessee 60.94
My seats on the first deck off to the side of the end zone. Face value $47. With annual maintenance fees for my PSL it comes out to about $50 per seat. I was offerred an upgrade to the 40 yd line and the price went up about $5 per seat. $52. The most expensive is the plaza, club and loge club seating. Those give you access to the huge lounge and bar area. I like my field level seats. Never get rained on. Close to the action.
As for rowdy fans, I don't see any more there than I have seen at any other stadium.
Personally I would consider it absolutely stupid to wear opposing team clothes to a game. There is always some a-hole to make a scene over it. The only exception is SF/Oakland baseball or football. It is still the Bay Area and fans really don't mistreat each other overall. More of a friendly rivalry. I have worn Oakland stuff to SF games many times and saw a lot of Niner/Giants fans in Oakland. Not much stupidity.
I went to games in Pittsburg, Miami, SF, Arizona, and LA. I went wearing neutral clothing and quietly rooted my team on. The people around me knew who I was rooting for, but I didn't make a deal about it.
As for Candlestick Park. It is a huge piece of crap. I will never go to another game there. In the winter, more than half the parking lot is under water or mud. Two lane road in, two lane road out. Colder than any other place in the Bay Area. They need a new stadium real bad in SF. I have been to about 4-5 niner games there and about 50 Giants games. No more.
Paying for a license to buy season tickets is ridiculous, but Al Davis started something that is beginning to pop up everywhere. PSL's.
I hope when I renew in a couple years, they won't charge me another $1000 per seat for the right to buy tickets. I will still pony up the bucks and do it anyway, but I would prefer not to. It's hard to be a loyal fan.
