umm...lets see here.....if you're in canada then I'd say Wemf, Om (which you've been to before), teknival, ummm.....there's lots of little festivals around here...
but the best one I would suggest would be Burning Man
That's held usually the second, to last weekend in october, and it is in the middle of Nevada desert in an area called Black Rock
It's a week long festval, you must bring enough necessities for the whole week or you're not allowed permission to enter....everyone gives something to the community for that week (this girl shaves your face, so you give her fruit, and this person is giving out shower water,,,,and this person is doing palm readings.....)
here, you'd have to check it out for yourself, it's a dream come true
