Slalom boating anyone?

Out west here in Ca, we are finally enjoying an albiet slow but
increasing popularity in whitewater slalom races. In Kernville last
summer there were over 75 entries in K1 C1 & C2. Is it growing in the
East coast (US) as well?

I bring this up as it is very hard to find used slalom boats here in
the west. The new ones all come from Canada and Europe. Is the used
market in the East the same?
