Can confirm how awesome regional burns can be. I've never been to the "big burn", mainly because the expense and distance would make it very difficult for me to attend and actually participate in any meaningful way.
I live on the east coast of the US (can't imagine how much harder this would be for someone who doesn't even live on the same continent) and while I could probably budget the money and time to attend, it would be prohibitively expensive to bring much in the way of a camp.
But I've attended probably 10 or so burns of varying sizes on the east coast and I truly love doing so. It's still an undertaking but I've been able to collaborate with friends (as well as make lots of new ones) to run theme camps. It's an awesome outlet for our creative and armchair engineering efforts and with so many people from different backgrounds, there's so much to learn and be inspired by.
Just seeing some of the great ideas people come up with has helped me to become more confident in trying out ideas that otherwise would have never gone past the brainstorm phase. It may sound a bit rude, but when I see the art projects and interactive games and installations or just fun things to do, I think "these are just other regular chumps like me...so why the hell can't I do something cool for once??"
I think of it sort of like playing an instrument or singing. At some point, there can be validation and motivation to be found in performing in front of an audience. It gets you to practice and refine. It makes you feel good to share with folks who appreciate your efforts. And at burns, I can chat with people who think our interactive lights are awesome or are thrilled that we brought our karaoke gear out into the woods, or are eternally grateful that we are frying up wings and fries for anyone in need of a hot snack at 1am.
Then you multiply this by hundreds of people who also create spaces to dance, lounge, eat, chat, interact, play, or gape in amazement at what you can build when you get a bunch of nerds and hippies and engineers and chefs and artists and musicians (and just random people who didn't even know they had a talent) into the same space.
It's like summer camp for grownups. It's tons of work and tons of fun and I can't think of much else I've done that begins to touch the positive takeaway I bring home after each one (even if it's just learning my limitations).
