two earth bumper stickers. I'm not sure who Martin is, because the website is now defunct, but I'm going to guess he's a member of the Green Party. Although, given his protest of Arizona SB1070, Martin might also be a Democrat, but certainly not a Republican (hence the peace sign).
Also present is a Creative Community Housing Project sticker. According to their website, "CCHP is the Artist-In-Residency program of The Creatives Project (TCP).
We are dedicated to supporting the day-to-day lives of creative
individuals. Understanding the financial stresses associated with
pursuing a career in the arts, it is our mission to offer creatives
various levels of support while nurturing the arts eco-system through
arts education service." Is it me, or does the word "eco-system" (sic) stick out to you?
So, he's an tree hugging, looking for free-space hippie that likes art but can afford to drive a Prius. Makes sense that he lives in the O4W.
