Sounds fun :)
A1) The best event I've ever competed in was when my XC competed at the state meet my senior year in high school. Second would be playing against Woodbury in basketball in middle school(I joke, it was stupid, he was 6'11 and nobody else was over 6'0).
A2) Best sporting event I've ever been to was probably the olympic swimming trials down in Omaha. Wowsers those guys/ladies are good!
B) Still my first competitive game as U21 coach, when we upset Portugal it really gave me some great confidence for where we were headed :)
Looking forward to others answers!
