Dragonpilot gave you great advice.
The advice I give anyone looking for a last minute ticket is 1) tell all your friends, family, and co-workers you're looking, so that when they hear something, they'll think of you 2) request your time off, but have a backup vacation planned in case you're not allowed to give those hours back, and 3) start making a packing list based on the items listed in the Survival Guide linked below in my signature. There are starter lists in the guide. (Newcomers who don't
have a list get overwhelmed by how much there is to pack or shop or think about, even if they find a ticket).
As for tips for next year . . . add yourself to the Jack Rabbit Speaks
email newsletter (great info and updates there).http://www.burningman.com/blackrockcity ... lists.html
And seek out regional groups and contacts. It can only help.http://regionals.burningman.com/
