Kenmore Air in Seattle does training in Super Cubs, a C-180, and the
DeHavilland Beaver. I was in town for a weekend over the Summer and
took a lesson in the Beaver just to get to fly one. It was a great
experience, although it's a bit expensive to be flying an 8 passenger
450hp plane for dual instruction. If/when I go back I'll try to do the
rating in one of their Super Cubs. I'd highly recommend them to anyone
wanting to fly a seaplane.
