At the end of this month, I'll be working the world's largest 3 day SP tournament and there's more teams coming this year, than any other year in the past. Last I heard, 475 teams have entered compared to last years record of 437.
It's an ASA sanctioned tournament.
All we have is ASA in North Dakota for SP and FP except high school (they do use the ASA ruleset but umpires wear blank shirts/hats).
