And that rideshare board link is:
http://rideshare.burningman.com
Green Tortoise is not as expensive as it seems--they are providing food, water, shade and transport/gas (you provide tent & other supplies) which--because of volume--is actually cheaper than getting your own of each of these things, usually. (You can add up what those things would cost you alone and see.) They're also taking a lot of thinking and worry out of the whole experience, which is worth something too. 'Cause it's not like a rideshare is automatically going to provide you with shade or camp with you--unless someone on the rideshare board has space for you in an RV. Then, it's going to cost as much as the Tortoise, but you might have shade + the whole week at the burn, which is the ultimate. (The biggest downside to the Tortoise--that I know of--is that the trip is only 5 days.)
So good luck with the rideshare board, it's probably your best shot--but if you choose the bus, don't imagine that the Tortoise people are robbing you blind.
