Club Meetings

Annual Potluck Party & Sell-A-Thon - 1:00pm Start

This meeting will be moved up to a 1:00 Start time. There will not be a jr rockhound meeting in September but Jr's are encouraged to attend with their parents and there will be a break while we have our membership meeting. This will be a Pot Luck meeting starting at 1:00 and our annual SELL-A-THON will start after 12:00 as soon as dealers are ready. There will be tables inside available on a first come first served basis. Inside dealers can only have one table each so we give everybody a shot at an inside table. There will be tables outside for dealers and they can have as many as they want. Set up will start at 12:00 inside and outside.
