I came across one like this in Genesee County (Hiker Willie's cache 'Genesee County's Easiest Multi-Cache' GC314NZ).a while back. I may not be clever enough to come up with something like this on my own, but I have no problem borrowing someone else's idea. I figured Roscommon County needed one of these. Thanks to backwoodslady for the container.
There is no room for a writing implement in the cache, so bring one of your own.
