There are never any dumb questions, thank you for asking!
Just to add what Craig has already said, we have two levels of membership here. The registered user level and the paid membership level.
Our "Member" runs are for those that have paid, a little something extra, along with other social events through out the drive season for those who have committed financially to DCMM (A non profit club). Paid members can also join our open runs.
The open runs are for anyone registered at DCMM, or are members of other clubs. We try to have one open run, and one member run, per month during the drive season.
The RSVP amount is up to the drive leader and can fluctuate if a run is particularly popular. Please let us know if you have any other questions, we're happy you're here!
