Sloss Furnace is badass and totally haunted.
Food Not Bombs in 5points at the satanic pentagram fountain serves food every Sunday at 1pm.
That area is packed with homebums so you are unlikely to make money busking or spanging unless you're pro.
Plenty of abandoned houses and buildings in Northside and Downtown.
I know a spot I've brought 2 friends to and they've made $100-$185 an hour flying a sign.... All that old Alabama money and Christian guilt.... My best pal's first kickdown was from an old woman wearing pearls, gave her a $50 and said "God bless you sweetie-pie!" Hahahaa.
I live in a punk house in B-Ham, we do shows (crust, metal, punk), garden, cook badass dumpstered vegan food constantly, but after being fucked over too many times and being disrespected I am unlikey to take you in unless someone I know can vouch for you. Sucks it has to be that way but I'm getting fucking jaded as I get older and my patience with idiotic shitheads is gone.
