Found a cell phone on a mountain ride along a wide trail/water dept mountain road a couple of years ago. Pressed the speed dial and got the guys wife in another state, who was extremely worried as the guy had recently had an operation and should not be hiking. We got the Sheriff involved, and they were just beginning to launch a search and rescue, when the guy turned up in the parking lot. I had passed him (one of many I passed) on my bike, but he made no overture about a lost phone. He had gotten a ride down with a Water Department truck.
