Some Kind Of Jam in Kempton, PA

a few questions about this fest... I am def going no matter what, along with All Good in July which I am completely stoked about. But first question, anyone here going to some kind of jam in pa? Second question referring to substances, bring my own? Or can I get some there? and 3rd question does anyone have pics of their trips to previous some kind of jams? I love looking at festi pics and dreaming about what it will be like. I cant wait for it, its close to home and I can meet some like minded people that live near me cause there arent many around me rite now. thanks for any help!!
