I like pro sports, especially football, baseball, basketball and soccer...but I only see any of them in person once every couple of years.
I did catch a Knicks game in the Garden last year, which was pretty awesome, and I've enjoyed the handful of times I've been to Yankee Stadium and old Shea (haven't been to the new Yankee Stadium or Citi Field, or the Nets' arena either). I've seen the Red Bulls play a couple of times up in the Meadowlands, and that was OK, too. I've never seen a pro football game live, but I wouldn't mind.
I saw ONE NASCAR race and one was AT LEAST enough for this lifetime! Talk about abrasive drunks and loud noises!
