Thanks for sharing this!
We’ve not personally encountered it, but read about it recently in a cache we were going to attempt. A cacher noted they ran across a trap en route to the cache, luckily saw it, and then backed away and abandoned the rest of the trip. Living along a river, years ago, encountered muskrat traps frequently, especially near houses, where the homeowners were trying to protect their river banks, and hunters were after pelts.
No idea of trapping sport, seasons, laws. Like gun hunting, knowledge of this would certainly be valuable.
Chuck Taylors are not good footwear in the sticks.
