WJ, the dues were set during the first meeting 2 years ago, by the members. It may or may not be fair. If the members want to adjust the dues, all you need to do is get a majority to say so. The dues were set low intentionally so as not to scare anyone away. Charter members dues cannot be increased as per the voting members.
It's a good thing you sent yours in early, I was looking forward to "busting your chops".
Oh yeah, A couple and a family (kids under 18) are the same, $35.00
