Welcome aboard! Glad to have you join. The best way to get involved now is to keep working your idea of a membership drive. I have not done much this summer due to schedule, but the big priority is to gain some membership momentum.
Since you see several boaters come through your yard, that seems like a good chance to spread the word about our grass roots effort to have a voice at the harbor. I will make up some more cards if you want to hand a few out at Exit Marine.
Also, if Exit Marine would like to sponsor some of the costs, you can wear a sponsor badge on your profile. In any case, membership is free, and having a voice at the harbor office is priceless.
