I agree with Francine.
The best thing we did in past years was to quit moving around and found a home. It gave us an address, so to speak. People knew were to find us on the 2nd Saturday of the month. Before that one of the major topics was alays where we were and how to get there. Once we established a base we grew.
Plus, while we have a nice size Harford county and north group now, 90% of our members come from a lot further south with less than 10% or so coming from Baltimore and north.
