After feeding our cats this morning, I let one of them, Molly, outside. I went onto the back deck to scan the back yard and driveway for her, and I spotted a rather large opossum waddling along the fence in my neighbor's back yard. His trajectory led him into our yard just as Sarah was getting out of bed, so I went in to tell her to come out and see him. By the time we got back to the deck, he'd moved on from our yard, but Sarah spotted him heading along the same course, essentially following the property line skirting a small forested area. I still haven't spotted Molly, though.
