James, don't hang your head! I too was a university cheerleader and in looking back, am very proud of that. I made some great friends--it was almost like a coed fraternity--and some great contacts as well. I had some super, never-to-be-forgotten experiences too!
I have 2 daughters cheering for coed all-star squads now. If they want to go on and cheer in college I'll support them but I'd insist that they pay a liiiittle more attention to grades than I did!
