Thing is i\'ve got a buddy who has a N2O liscence and goes to some shady spot to get it filled. Hes got a huge tank that is like 50 lbs or something. I personally don\'t have a tank and wouldn\'t be able to drive a 50 lbs tank 2 hours to the show. If i could get my hands on a smaller tank i could easily get it filled. Don\'t have any idea how much they cost or where you can get one. Anyone has any info feel free to let me know.
