Although members come and go, active membership has been steady, varying between six to ten members over the years. Membership is open to all who are interested in two-rail O scale model railroading, and who are congenial with other members and participate in promoting the goals of the club. Having a set of modules meeting the specification requirements while desirable, is not mandatory. Those interested in discussing possible membership should send an email to orangecounty.oscalers@gmail.com.
