Graffiti: First steps

I usually go out on my skate bord or bike and just take note of all the abandoned building around town. I just got a can of black spray paint after the cops stopped me last time. Planning on using that to make a few statements people won't ignore. I will wear a thin jacket and a draw string bag underneath so I can change just in case the cops get any calls I can just change and deny any involvement. I got a bench with some anti-homeless architecture, an old bank, and some random building that look like it is older than me on my hit list.
