Umm, well I did it for EDC last year and I can safely say acid is NOT the kind of drug you want to be on when there is that many people around. Its more of a mind and perception altering Drug then a "feel good" one. If you still want to do It I would recommend doing both E AND acid. This will keep you in a good mood no mater what and you'll still get the alterations in the music. for dosages I would take 1half the normal dosage of each and take another half-hit of E after 2-3 hours. If for some strange reason you start to freak out just sit in the middle of the bleachers. hope you enjoy it
