I spent a winter in Missoula back in my college days, and while I was there I got to participate in an urban-design charette sponsored by the American Institute of Architects. We put together a 100-page report over the course of a single weekend, quite a challenge in the days before personal computers and digital cameras. It was all kinds of fun.
The report definitely looks a little ragged by today's standards, thanks to our lack of technology. I remember, though, that we were all particularly happy with the photo we chose for the report cover ... we decided that it captured the essence of Missoula as well as anything.
I don't know which member of the charette team took the photo, but here it is. It might be the underside of Missoula's old Orange Street Bridge, which was demolished a few years back.
