We walked toward the pedestrian bridge at the UofM. This and the next puzzle simply broke me. I don't even remember how we solved this. We didn't. We just spent our money outright on the answer. I have since lost the paper we were working on. We worked sitting on a bench inside the pedestrian bridge over Washington. It was a hotbox. I flashed on being tortured, trapped in a cell while they extracted information from me. but I didn't know! I don't KNOW! How could I? The puzzle was too much! After all my optimism and sense of excitement, my spirit foundered a little here. In it's own way, that was cool, because it means I felt a real range of emotions. Nobody likes being disappointed, but it was still worth it.
