Having reversed this move, I'm not sure if I would recommend it from a purely boating standpoint, or from a skiing & boarding perspective either.
That said, Colorado has the playparks and the camaraderie and what not for the afternoons, and much better town-accessible/roadside boating & other options for quick fun. Denver has Gore Canyon and Bailey when it's dry. The entire state is blessed with great boating & scenery when the water is up.
Whereas in CA you usually are boating in isolated areas, in isolated groups, or on dam releases with other boaters, but you are still a far cry from a real town: Belden Town & Groveland CA come to mind. Too much freeway driving and sketchy, unscenic "foothills" driving. Of course it's always worth it, (unless you get skunked) but it's nice to sleep in your own bed sometimes after paddling, like they do back east, where the paddling is more civilized--but that's another story.
Beware of getting lured to the NW by Todd, he must get a commission for every boater he recruits to the NW from MTBuzz, as he's always on here (and elsewhere) talking it up as this eden of pool-drop boating in a moderate, maritime climate, with an abundance of fishy, wholesome foods. A little dreary maybe, but that's okay because in Seattle
they sprinkle Percocet
into your coffee when you're a wounded kayaker
. It's more than good, move there now. Put some Range
into your Life
I've never boated rivers in the NW but it's funny that TG doesn't ever talk up all the frozen drysuit action, ice-slicked logjam portages, and all the other miserably cold & woody things I hear about boating "year-round" in that part of the world.
Fun stuff, these semi-frantic "where to live" posts.
