It's $30 for parking now. Prices keep escalating. Parking for the Marlins was $15 at Sun Life. Like you said, it was $25. But it went up for the Dolphins because win or lose, fans will continue to hand over money for bad football. It's not fair to the fans.
I brought up tailgating because that's just me. You're right, it is totally optional. For me I feel like I have to do it because I couldn't tell you the last time I went down to Lauderdale for something other than a sporting event. Tailgating is my chance to see my friends back in Florida and have a good time with them. If we win, GREAT weekend. I'm only doing one Hurricane game in Miami this season and it's because administration is doing nothing to make that program better. I've cut my yearly donation to the University in half. More than half. And the only reason I'm doing even one game in Miami is because Florida State is in town and I'm not ending my Miami v. Florida State streak every though everyone knows the Seminoles will drag our dicks thru glass in October.
$500 is well beyond most people's means. I agree. Ticket prices for a bad football team shouldn't be so expensive. You're wanting to put asses in the seats, start by lowering some prices throughout the stadium. I walk in the team store and prices are inflated. I can get the same shirt for 20% off online. Technology has hurt stadium revenue. I own a 70" TV that I can sit in front of to watch the games. NFL Sunday ticket. Tons of sites (though illegal) to watch games on. Cook my own burgers for a fraction of the cost. No traffic after the game. I get replay when I want. It's very convenient these days to stay at home and watch a game.
