Why don't you come to Confest? That is if it is on next year. There is usually skinny dipping, body painting, yoga, tai chi, steam tent , silent disco and workshops. Anyone can hold one. I usually hold one on starting a vegie garden for beginners. Confest is clothing optional.
I checked the Burning Man website. Wow....it's even worse than I thought. Rules, rules, and more rules. Probably not bad in all, but having someone going through my stuff before I go in is always a deal-breaker for me. Expensive, too. $400+ for tickets, and then the added expense of getting parking tickets, etc. I'm not sure if parking is assigned as you go in, or if you can choose where you want to park or not. Not willing to find out at the gate. There are way too many things I enjoy that can be done elsewhere with far less hassle.
