Urban Exploration
I've always been completely fascinated by deteriorating architecture and infrastructure and was stunned to discover that there are groups around the world who explore such structures. There is a local group called "Action Squad" (which I believe started at the UofM) and they've discovered some pretty interesting spaces. I figured their site could provide some ideas for our class, and lo and behold there are some fascinating structures! (Check them out on this site: http://www.actionsquad.org/ruins.html)
I thought that the Gopher's Munitions Plant was particularly interesting and could provide an interesting backdrop for an art project. http://www.actionsquad.org/ulands.htm
