WoW's yearly "rally" called the "Ride In" is going to be in Stratton, VT this year. I guess that's the closest it's ever been in the Northeast. Unfortunately it is during the week (July 6-8) so I don't think I will be able to go.
I was/am also looking for other women to ride with and thought this would be a good opportunity. I wanted to attend a meeting AND take a ride with them before I joined. I think both are important because in the meeting you get a feel of what the club is about, personalities and the group dynamics. During the ride I got to see how the leader would handle the group and the group riding dynamic. I liked what I saw and a couple of the women were very friendly, I even went back to one woman's house for lunch!
I would research clubs in your area and then contact them to attend a meeting and a ride. I am sure that all area clubs are different in their dynamics so you would want to check it out first.
I'm not much of a "joiner" and I don't usually like group dynamics but this group does seem like a good mix of women and I like their camaraderie.
