I actually went and watched the US Championships that were held a month or so ago here in Tempe, AZ (at ASU).
My buddy is good friends, from college, with Tim Sweeney and Doug Ganim, who won the 40+ national championships. I guess at one time Sweeney was ranked the best in the world, but got bored with it and primarily plays pickle or something... He says he couldn't find any real competition in Chicago. We had dinner with these guys, and I thought it was pretty funny, but they had actually had groupies...
It was pretty crazy to watch, these guys are so good it was crazy. I think Sweeney broke three racquets during one game... I probably won't go back though.
