So, the same evening as the lynx sighting... we had this great big coyote prowling around. watching us from the hillside, wondering when we were going away (inside). that, or stalking the neighbor's cat? (Jeff pointed it out, and they called Romeo in for the eve.)
Upon further reflection; I had left the baby pool, on the patio with water in it for a few nights in a row... could it have become a watering hole for these guys? More convenient than the water hazzards on the golf course?
