I epoxied pot metal wheel stops on each of the rails at the ends of the six sidings on my raised outdoor steam track. Over time, they had lost their shine and became almost invisable in the natural hue of the rest of the layout. For the past year, a family of squirrels had been using the layout as a short cut from their home in some nearby spruce trees to the big maple in my back yard. It was common to see several of them scurrying along the tracks and leaping into my inner fenced in yard. The other day, while preparing for a fall run of my K-27, I noticed that both the stops in the steamup bay had been knawed almost to the rail. I checked the other 12 stops and lo and behold, they had been almost completely eaten also. Given the warnings that accompany the stops when you buy them from Ozark miniatures, I think I might have a few sick squirrels. Is this a common happening?
