I'm looking for a place to host somewhere between 40 and 100 people four a four-day not-too-rustic camping/retreat weekend next summer. It should be north of Big Sur, California and south of, oh, Grants Pass, Oregon. It shouldn't be too hot or windy (higher in the Sierra, in the Cascades, the Trinity mountains, the redwoods, all good; Turlock, the beaches of Sonoma County are less good), it shouldn't be especially expensive. It should have space for tent camping and rustic bunk/cabin things. It should have space for group cooking/eating, ideally with a sink and stove, even if rustic. It should have pit toilets or better. It should have a firepit.
Also helpful but not required:
Electricity *somewhere* -- in the kitchen is fine.
Water nearby for playing and/or swimming or splashing
Open space for frisbee, etc.
Sheltered gathering space.
I have a year to plan, and will entertain many ideas, I've just never planned something like this before and am not sure where to start.
(too fancy, we don't need conference rooms, etc.)http://www.allaboutretreats.com/centers/norcal3.html#silvermtn
is okay, but something a little less remote is ideal.
