@bipedalist, @JKH Thanks for your
replies! Yeah, this is stuff in the yard, not the wild area. Usually in areas where I've been gardening, mowing, etc. Sporadic, unpredictable.
Attaching two photos from last year(I think.) This is by our pumpkin patch. Last year a branch appeared in summer (where I had been working on the mower) leaning in one direction. I had to move it out of the way for the mower. In fall it reappeared leaning in the opposite direction. May have been the same branch. I get stuff like this. You notice it because it's an area where you do yardwork.
