Yep, counts as a sport! I'm interested in trying out for the team, too. I hear it's slightly competitive because it's not a team with many spots...20 or so people make up the team, if I recall my facts correctly. Members of the team range from people who have ridden competitively for many years to those who have only ridden a horse a time or two.
As I am not currently a cadet, that's about all of the info I can give you regarding the equestrian team...I am simply interested in the equestrian team as well!
Are you an accepted candidate as well?
