So you want a healthy local scene? Go to shows, spend your money to pay the bands, cheer their songs, talk to the people there.
Help create your own surroundings, if you do nothing then you'll get nothing back in return, and certainly what you deserve.
Don't be so lazy and closed-minded that you'll get so stoned you lose interest and only support 'the music you love' because your friends have told you to come or risk being ostracised.
Likewise, don't feel so afraid to go somewhere on your own and see a band, because once you're there, it's going to be easy enough to make friends anyway. Such is our nature.
Stop talking the talk which makes you look cool and fit in to the scene you chose to boost your attractiveness to the opposite sex.
Start giving a shit and helping out the people who are in this for life and who make this their everything.
