Unfortunately, $$$ wouldn't allow me to go this year, but I'm already saving for next year!! I believe you'll find more planned for trikes next year - there is new "management" in TRI (note the 2 trike courses this year at Americade), and I'm sure they'll be more involved. I think part of the problem has been a lack of participation in TRI with trikers in the Northeast - they haven't been that common around here until recently. With triking taking off up here, and more "triker" activity on the various forums (Americade, TRI, Trike Talk, etc) I'm sure TRI and Americade will both start having more things planned for us.
Anyway, that's my two cents, for whatever little it's worth, with a sprinkling of crossed fingers and wishing thrown in.
