I’ve autographed more than one aspen tree in our travels.
Personally have never found anything weird in the woods while hunting, but a buddy found a Winchester lever gun that a tree had grown around over the years at the current Osage Western Wall WMA north of Pawhuska. He cut out the section and made it into a coffee table. He’s passed away now and have no idea where that went.

apparently, it happens; wonder how many more are out there.
