Chicago winters are legendary for being harsh. What made you decide that camping on a roof was the best course of action?
I was inspired by Habakkuk 2:1 ("I will stand at my watch and station myself on the ramparts; I will look to see what he will say to me, and what answer I am to give to this complaint." NIV) and decided that in order to deal with an extreme situation like violence, I had to do something extreme to draw attention to it. I'm here until all the funds are raised.
