I like the Camp Harmony idea, Joe.

I agree that the best location would be something near major transportation routes (airport, interstate or train or all 3). I love the Northern Calif. Coast or the Big Sur area, but places there are not quick or easy to get to, even after you've flown to the area from Portland, Seattle, Boise, Denver, Phoenix, etc.

The Sacramento area has less traffic but it a lot hotter in the summer.

If I did have to spend 2 or 3 days or $250 each way to get to the gathering location, I'd want the room and board to be very cheap to make up for that.   But it would be nice if I didn't also have to go buy a tent.   

I agree the West Coast gathering doesn't have to be in the same location every year.   

The "movable" feast idea has its merits too.    We did have a great time at JenEllen's in 2002 with only about 10 of us in attendance.   And it didn't take most of us terribly long or cost us an arm and a leg to get there.   (Speed demon Amos drove straight thru from Ellensburg, WA, to San Diego in about 12 hours, but he's the exception.) ;)
I imagine some of us would be able to make it to two or more smaller Mudcat gatherings in the same year, too.
