I'm sure you would be open to some groups wanting to go off to do their own thing ..but still retain a coalition of common interests.

ie. The university/college cyclists/walkers might want to form their own group for a range of reasons since they could offer on-campus events/service to the students. Their funding source might be drawn in the future, from other sources..

It would be useful once your core group is established with its bylaws and membership base, to become a member group of a larger advocacy group for broader campaigns.

You have much energy.

Make your first event and ride a good one! Christmas is coming up...every one is in better spirits..
