Two weeks ago wife, friend & I went on a nice 58 mile ride from California to Oregon and back.
Partway back, my wife realized she's left her water bottle in the parking lot of the restaurant at which we'd had lunch. We decided not to go back for it.
The ride was so nice, that we did it again last week, and when we pulled into the parking lot, there was the water bottle. We were actually famous in the restaurant, since the staff had been debating whether we'd ever come back for it.
