My eighteen year old daughter loves everything about horses, horse shows and everything associated with the word ... "horse". She loves the smells of saddles, the sensation of landing the perfect jump, the nuzzle of a muzzle and even the endless waiting (and build of anticipation) at horse shows.
However, my seventeen year old son would rather eat dirt than step a single sneaker into the barn. He'd rather gargle glass than go to a show. Riding a horse would be less welcome than a Zombie Alien Invasion from the putrid planet of "Puke"... or whatever video game scenario applies.
While my daughter is tearing up the show ring and will jump 3 or 4 foot jumps a top her hay fuled steed, my son is shredding rails, slashing through snow and jumping 30 foot jumps aboard his gravity powered snowboard.
He loves the cold wind in his face, the feel of the ever steepening terrain as the evergreens blur by. He even enjoys the thrill (and great story) of the occasional crash.
My daughter, on the other hand, would rather eat dirt.
