Holy crap you will love Burning Man. I've been a Burner since the late 1980's, and know Many People. I have Opinions. I shall assail you with all of my Opinions and Contacts at whatever time you choose. :-)
It's been something that I've been wanting to do for the past 2 years but after going to this regional (which was basically "fun camping" but I got a better feel for the people and they're awesome) I'm gonna make it a real priority for next year. Kinda changed the dial to "I'd like to go" to "I have to take steps to make it happen" :) I'll definitely PM you once plans to go are more concrete but I'd love to hear your Opinions anytime. Honestly, I think many people here would be interested. It should be it's own post whenever you have time man!
Too bad you are in Montreal... I have a really excellent Burner friend in Toronto that would be a great resource for you. I think you guys would hit it off. Burning Man is just ... so much of everything ... I'm not sure a single post would be very useful. I did write a bit of an expository piece on how I got involved with Burning Man, and my experiences there. Check it out if you want some history.
