I attended a Bozeman City Commission meeting earlier this week. It was the first such meeting I've ever attended. The meeting started at 7 pm, and still had a few agenda items remaining when I left at 10 pm.
Here are some relevant links: Agendas, Minutes.
If you are interested in development happenings, you should attend some of these meetings (or at least read the Agendas and Minutes). I learned about the new Lowe's and the proposed Best Buy on N. 19th.
