Just want to say, that any real professional barrel racer (or other horse person) would have been polite and waited their turn. Besides that, if you can't ask your horse to stop in the middle of a barrel run than you don't have a very good horse. And cooling off is SO important! Wow, that really got my blood boiling. That is how barrel racers and barrel horses get a bad rap...from people like that.
Don't squat with yer spurs on!
