It is a good subject, though, as it would be nice for items to stay around rather than fill a landfill while they are still in good shape. Money aside, it would be nice for some things to carry on.
I have a module that was on a museum layout originally that has passed through several hands. I plan to enhance it but pay some tribute to the original building who has likely passed away.
Donate to a local club or kid that might be interested in the hobby seems like a good approach to not just fill a landfill.
Who knows - classic cars that were left to rust in barns are suddenly worth serious cash again...
