Where to open a kayak retreat?
Lets say I wanted to open a kayak retreat center similar to the Otter Bar in California or Small World Adventures in Ecuador (for the moment lets limit this to the US)
I'd want relatively cheap river-front property, on a river that has a very long season (and preferably isn't ridiculously cold run-off all season). There should be many different sections of river of varying difficulties (II-IV). Relatively remote would be good but I'd like to be able to go a decent grocery store within an hour.
Added bonus (but not required) if a large hub airport is within 2 hours. And rich people who kayak nearby (4 hours?) is always a plus but not required. Also added bonus if I can diversify with bike tours or something similar.
Where in the US should I be looking? Some ideas I've been to:
Ohiopyle/Confluence PA: Good rivers, really long season, good airports, lots of rich people, possibility for bike tours (though a crowded market right now) but not very remote, very hard to buy property in Ohiopyle and less good river access in Confluence.
Buena Vista/Salida/Cotopaxi CO: Great rivers, great play parks, decently long season, kinda expensive, not very remote
Poudre Park CO: Great rivers, short season, fairly remote, hard to buy river front for a reasonable price
I obviously haven't been to many parts of the country to boat so what other areas should I look at? Awesome rivers with a long warm season that could be a "destination" would be the primary criteria that I'd want to hear more about.
American Whitewater river info you can use.
