Another venue to consider would be darkroom visits. Particpants would come to the hosts house for a tour of the facilities, maybe some printing, maybe a potluck meal and print viewing. Whatever works out to be fun and entertaining and possibly educational to entry level members. When my basement is cleared of the furniture stored by the children just getting out of college and married we can set my lights back up and try some studio work. For that a volunteer model or two would be fun.
