Yah this august was my first time going, and I plan on going every year (I already bought my ticket for '10 haha) It is absolutely amazing. I would say that if you can go, love trance-ish music and meeting amazing people then you would have a great time.
i'm heading there in 2 days! i can't wait, it'll be my first time... bassnectar, excision, fungineers, ahdam shaik, gaudi....so many awesome preformers! i'm all set, 1 qp of shrooms, 1 oz of molly and a whole lotta liquid lucy: at least one jedi flip is to be expected!
I've never gone either, hopefully this year will be my first.. that is if I can get a new goddam job and have money in time before the tickets sell out! AIE! I'm sure I'll be fine though.
I have heard many wonderful things about shambhala from friends. And perhaps for 2011 I'll go check out burning man
