I would find out who he was/is and send him an image or two thanking him.
He told me his name, but of course, my addled brain didn't hold on to the information. But hey, I know where he lives! LOL.
I do intend to take him a couple of prints and see if I can get permission to hang out there, as I'm betting there will be some other interesting things at that pond over time, and maybe I can also find out more about the Eagles and whether he can get me on to that land as well. That would be awesome.
