Most campgrounds use binder clips or clothespins to hold receipts. At the James Kipp campground, located between the east end of the Upper Missouri River Breaks National Monument and the west end of the Charles M. Russell National Wildlife Refuge, they use mouse traps. Maybe they have a rodent problem.
Or the wind is strong enough you need that kind of spring to hold the permit in place.
ReplyDeleteRust has caused the trap to loose much of its springiness.
