My wife and I are looking for recs, travelling out of NorCal.

Requirements:
1) 6 hours or less travel time (one way) from San Francisco Int'l. I checked places like Costa Rica and Belize but it's longer than that.
2) Access to MTB trails and trail running (wife).
3) Not too hot. I considered Moab but it looks way too hot.
4) No camping or rugged accommodations. Wife's not too keen on that.

During the past 2 years, we've done Deer Valley and Whistler. Both fit the bill perfectly. Some current considerations are Boulder, CO, Alaska, maybe Yellowstone/Tetons. My concern with Alaska (Denali) and Yellowstone is that the MTB'ing may be restricted since it's a Nat'l Park. We're doing Hawaii w/ the family in Oct so that's already used up. I'd like South/Central America but can't figure out sub-10 hour travel time. Also, it appears to be the tail end of the rainy season down there.

Thanks for the help.
