i dont know about best, but the only 4 20 fest i've been to is cavefest down in southern illinois. its a great venue, a natural ampitheater in a salt petre cave which projects the sound and sick light shows on the rocks. theres also a rave tent. the whole scen can be pretty hectic, a lot of energy with kids comin just to party from surrounding cities. but its on the shawnee natl forest, so you can really camp as far from all the comotion as you want. its beautiful down there that time of year
if you're in the southern parts, widespread panic is playing orange beach, al, three nights leading up to 4/20
Man, Im so down I have a drug test on May 4th so I stopped smoking March 18th. It sucks so bad. Have some fun for me!! = D
