Some regrets, some not...
Looking at the pictures of the peace marches in Washington and San Francisco, I kind of wish that I had gotten on the bus to DC Friday night. I went to two marches in DC last winter, in January and March, and while the all-night bus rides were tedious, the marches were exhilarating.

On the other hand, after watching the debate and reading some reviews, I don't think I missed much by not going to Detroit last night.
