Bear
While most of my neighbors have actually sighted bears frequently (especially the local beekeeper), we never had the opportunity to see the one we "had".
It started with my foolishly leaving some bags of horse feed in the barn overnight which, next morning, were torn open. Next night, with feed put away, half the hay bales in the feed room were thrown out into the aisle & tossed around like toothpicks. Oddly enough, through all of this, the horses were quiet, as the barn is quite close to the house & I would have heard 7 horses going nuts.
We then started noticing the bird feeders raided, especially of suet, & began finding large - to be polite - "scat" piles underneath our deck, all full of long coarse black hair. The footprints in the mud were the last piece to the puzzle.
Unfortunately, "our" bear met with an untimely end last summer. He was hit by a motorcyclist on the road right outside our drive. Turned out to be a young male, around 100 pounds.
Even tho he was a pain in the you know what, I miss him in a odd sort of way.
