Hey Gary, Sorry the camps are for LDMA members only. GPAA members can only gain access a couple of ways, you can be a guest of a member for 3 days, ( guests can only pan and sluice, or help the member tend their equipment (dredge/highbanker), you cannot bring your own equipment.)
Or once a year you can attend an LDMA outing for 3 or 5 days.
You can also apply for a 3 day pass to a camp from the office, you have to pick specific days and a specific camp, as it is not an open end pass.
Paul
