Nathan, I think this is a great idea, but weekdays will always be difficult. Since I live in San Francisco, it would be a lot easier if this was held on a Sunday, giving me (and perhaps others) time to drive down that way.
Ellen, Thank You for your input. The idea of doing this during the week was to see if there was interest. Kind of like "bike night" is on Wednesday night. Hopefully we get enough to continue. We also are planning, but have yet announced, a rally which will be on a Saturday or Sunday.
