Francine,
That is a very sad scenario, our club the Badgerland S Gaugers are also in the ranks of the Geriatrics, but we have been blessed, we found a permanent home for our modular layout. This was something desired by some of the club members for some time, but we could not find a location. We are joining with our club as an associate member of another local train club in a smaller gauge. Maybe if your club hierarchy would reach out and check with other local clubs this might be a possibility for your club also. It is very possible if you can hook up with another club, they may have folks with the DCC experience required to help you. I hope you might be able to find a location where your club can have a home.
