Here is an excerpt from the page for the event. I know there are a few people that are opening their houses and yards. I will see if I can get more information on that.
Tent camping on site will be on a first come, first serve basis. Please bring $10 cash to check-in, and note that we are located in a burn-ban area so bring a propane stove if you are planning on cooking. No pets are allowed. No smoking or alcohol allowed.
Harmony Grove also has cabins for rent from $30 to $60/night for two people. You can reserve one through them at either email@example.com
or by phone at (760) 745-9176. No smoking or alcohol allowed, but pets are welcomed here!
Since camping space is limited, we send a special request to all of our San Diego Permies to consider opening their house/yard (rooms, couch, or tent space) for out-of-town permies. You can charge $ 10-30 and donate part of the income to the Southern California Convergence Funds. Please see under "Forums" for requests/offers of hospitality."
