There's an old hollow tree that has a 3 foot arched opening on one side and about an 18" one on the other. I always expect to find something I might not like in there! Those details sure show well in b&w. I'm finding this fun.
What a neat tree! Reminds me of the one we walked through in Yosemite National Park. Yes, black and white sure brings out the unique textures of things. Wonderful lighting. I'm glad you came out of the tree unscathed, and I'm glad you're having fun!
