@Yellowstone Special posted:You guys kill me. Nothing wrong with a bulk load of real M & Ms in a hopper or gondola. I've had this on my layout for years, with a regular turnover of the M & Ms, thanks to grandkids and neighborhood kids (and adults) visiting the layout. A load of the real thing has been running around on my layout for years, with never a critter, thanks to a clean basement.
Nice!
This reminds me of when the Ace Hardware man suggested I use Gorilla tape on my lawn mower to cover a rust hole. When I said I was concerned that the tape wouldn't hold, he said, "just put another piece of tape over the hole if that happens." I had that taped mower for several years after that and only had to replace the piece of tape once or twice.
I your case, if the candy gets bad, or eaten, just put some more candy in it
