now after being in this culture for a longer period of time, i dont think it is about expressing yourself as much, it is just about doing what you feel like doing. school, life, jobs, all of that really stresses a person out, but when im on a roof painting, i feel free. and people who have a problem with me painting walls, trains, abandoned buildings, trash cans and other approved surfaces, need to chill out, i am applying a color to a surface less then 1 millimeter thick. i do think that it should be illegal, half the fun is doing the illegal stuff. it does come with consequences tho, 3 of my mentors were all arrested for it, and are facing felony vandalism charges(stiky rust & maus, you will be missed).
and at frenetic1amnesic, i am blond and white, and 8 of the 10 people i primarily do this with are white and from middle class families.
