I had a gift area in the open wound that was hollow in the trunk of a poplar. Yes, it was wide enough to get your hand in and place a peanut butter jar. Had some interaction within and about that. It eventually totally healed up sort of like another similar hole in a maple that I used to put my dogs ashes. I also had a log where various stick arrangements and placements were interacted with over a brief time. It happens! Any live animals gifted in return like box turtles put in compromised (immobile) positions? And, it rocks your world when it does! Obviously what goes on in these situations is that you are being closely monitored during daylight activities somehow, I have had extensive loud bird call medleys reproduced along with drummed cadences over time. So they are carefully listening during those same hours. I had a small wood carved figurine of a bigfoot like critter placed between two rocks removed and kept in same general gifting area. I used to encounter a specific shaped (trapezoidal) quartz rock that I think they were gifting in return, hard to tell they occur naturally pretty often where I am. It is something they suspected I was interested in, which I was. Long story short I travelled this country and maintained it for 20 years before I even remotely suspected the glimmer of a BF eye might exist. You would never think it could happen, until it happens to you.
