You set up your own club in a salt cave

Theirs nowhere for the under 21 set to hang. So You wander the beaches until you find a massive salt cave with great natural reverb. You and the band rig up a gate and hire a couple of friends to help you out with the operation. You score a keg of beer and you open the Secret hide out and charge a ten dollar entry charge. You and the band provide entertainment and build a rep. The place is a smash hit! All the kids on the island state visit at least once a month, some of them come every Friday and Saturday. The money is rolling in and you branch out into selling meth cola and hits of low grade X you scored on the main land. This nets you even more cash. You buy amps and new instruments.
