I have attended three Live UFC Events.
The first was UFC 120 Bisping vs. Akiyama - I was living in Europe at the time, but still had to pay a bunch for the plane, hotel, and tickets to the show.
The second was UFC on FX1: Miller vs. Guillard in Nashville - My financial commitment wasn't as much for this one. It is about a 2 hour drive up, grab a hotel for the night, and drive back the next day. The ticket was also not nearly as expensive for this show.
The third was UFC 145: Jones vs. Evans in Atlanta - Atlanta is about a 3 1/2 hour drive, hotel downtown, and good chunk of change for the ticket
After watching the fans at UFC 149 chant "Refund", and seeing a card get cancelled eight days out, and seeing post of several people who got burned... all I can think of is that I might not be spending the money on anymore live events.
Don't get me wrong, being one of 5 people in London cheering when Dan Hardy got KO'd by Condit was a great experience, but I also have a 55 inch TV in my living room, and it is much cheaper, and relaxing to hang out with some friends while watching the fights. I don't have to worry about the camera man, or ref being in my sight line, or having the drunk guy in the next section starting fights, or listening to the guy who brought a date to her first fight, and is trying (poorly) to explain the action and why she should care about the fighters.
There are a lot of fun things about going to a UFC live event, but next time they come to my region... I'm probably going to pass and enjoy the action from home.
