A collection of dubious top rope climbing anchors.
Ha! John, that first pic is my anchor. As I'm sure you know, this particular tree is a bit awkward to set up low on, given the extremely low angle between the rope and tree. My recommendation to others for this situation is to use a frictionless wrap to keep the anchor in place. While you can't see it from your pic, my anchor was not truly frictionless, and it did slip a bit over a handful of falls...not good for the tree or rope, and I would do it differently next time.
Missed by THAT much.
