I like attending baseball games. Football games I can take or leave.
Living in Cincinnati, costs are minimal for me. I can see the Reds ballpark from my office, so it's very easy to attend games after work. I also live 15 minutes away, so weekend games are no problem. With the team being terrible, cheap tickets aren't hard to come by.
I could give a crap about the Bengals, and am heading down that path for the Jets, so I have very little interest attending NFL games unless the ticket was free. I might splurge and get tickets on the 50 yard line close to the field for the Jets Bengals game in December because they should be relatively cheap and I likely won't ever do it again.
College football is fun, but I rarely go to games. I used to travel for WVU bowl games back in the day, but haven't cared in years. My wife works for UC and got free tickets for the upcoming game against Temple. It will be my first football game at Nippert, so I'm kinda looking forward to that. I did attend my first FCC game since they moved to the MLS the other day. It's kinda cool, but it's still soccer.
