well, you are going to a reggae concert, so odds are many many people will be smuggling weed in...why dont you just take a purse or a bag or something and put it in there??? no way they are gonna search every bag/purse coming in...shit odds are they wont even think twice about it...i dunno, i just wouldnt sweat it too much...but whatever ya do just keep it cool and youll have a blast.

wish i could help ya more....
