A variation: I was touring from Seattle to Cortez, CO. During the third day of the trip I took a ferry from Pt. Townsend, WA to somewhere I cannot remember. Got off the boat and started riding along. About 3 miles later I felt like I was missing something. That's when I realized I had left my Camelback hanging on a fence post after getting off the boat. Good thing I hadn't gone that far. I hate going backwards.
