That, of course, would be Porcupines & Quills.
No worries about a porcupine throwing its quills but this large male decided to make its way down to ground level during a busy time onto a potentially dangerous path. No danger from any wildlife, only the two-legged kind, including bicycles.
I don't know how it knew there was a lull in the action other than a porcupine's acute sense of hearing but having watched it for several hours from a safe & hidden location, I moved in to ensure it moved into another nearby tree and not an attempt to cross the path. This may have been its original intention because it climbed up a new tree and immediately slumped into a position totally out of the sun & the wind (Photo #8). Porcupines know best!
