We have 62 member families in the Orange County Garden Railway Society and keep growing.
We have monthly meetings that are potluck lunches or dinners at member's homes/railways. There can be and often are over 60 people in attendance.
Yearly membership is just $20 per family ($10 after July) and for an additional $5, you can get a new Club calendar of the member's railroads. Club cost is $11 and additional calendars can be had at that price if there are any left over. Basically all money paid in goes back out to the membership during the year and we carry no "profit" from year to year.
Starting in Jan, Club pays the month's host $50 to cover costs of plates, plasticware, and drinks (was $25 but we're getting too big for that).
We have large raffles at each club meeting. These are self-supporting with the proceeds from one month going toward the next month. In November when people renew and we reaffirm our Board for the next year, we always have a mega-raffle including several train engines and rail cars, buildings, complete starter sets, etc., etc., etc. Last week I won a "new" in box Sierra SD-40 sound card, and a Hillside Railways flickering firebox kit for just $10 worth of raffle tickets.
Because our Club is "supported" by BridgeMasters, the raffles get really good prices on stuff, especially from estate sales. We also have members who own Narrow Gauge Junction, Roecks, and run the Pomona Fairgrounds Fairplex Garden Railway.
In December some members have evening Christmas runs complete with a visit from the "Big Guy" and goodies.
We have a monthly newsletter that goes out to the membership.
We have some of the nicest garden railways around.
Our members set up a "garden railway display" for the Fullerton Railroad Days.
Sometimes we set up outings on the train to someplace.
