ive met a number of people in bands just by hanging out by the tour bus.
fieldy from korn
the drummer from limp bizkit
otto the bassist from limp bizkit
quick autograph from rob zombie, met his smoking hot girlfriend too
i got to shake hands and ask howard dean the democrat who ran for president, a few questions
i shook obama's hand (thats it, literally thousands of people swamping me trying to touch the guy)
john edwards, pic with him, shook his hand
all the members of the group disturbed, taproot, dope, 7/9 slipknot members, everyone from staind, yada yada
that is how you meet people though. they have to get on / off the that tour bus somehow...so they walk to it. and to walk to it, its exposed. so just hang out by the thing before / after shows and you can meet bands realllly easy.
