We had previously resolved that if we made it this far and didn't feel like continuing, we could call a taxi from here. Although we were a bit tired and footsore, we decided to go ahead and continue walking home over Thornton Avenue through Newark. If you went and looked at the walking map, you'll see that it's an open loop. That's because while walking through Newark and waiting for a traffic light, I looked up back and saw that we were at a stop for bus route 218, which also runs right in front of our apartment, and the once-an-hour bus was approaching. On the spur of the moment, we decided to go ahead and ride the bus the last 5 km or so home. We boarded the bus and I dug for my wallet in our backpack. (I was wearing shorts today, with no place for my wallet.) Bus fare is $1.75. I hadn't brought any small change when I packed my wallet in the backpack. Fortunately for me, the extra change from the vending machine at DENWR meant that I didn't have to waste fifty cents overpaying the bus fare.
The bus driver didn't notice that we'd pushed the "Stop Request" button for our stop and overshot it. "Oy! You missed our stop!" I yelled from the back door. The driver, who had been yakking away on his cell phone since before picking us up, made a quick stop that actually put us slightly closer to the entry to the apartment complex. I appreciated this, as my legs were starting to seize up after slightly more than twenty kilometers hiking today.
Including the bus ride, we got home just before 6:30 PM. We both think much rest is now called for. We can veg out and watch rugby matches without feeling the slightest bit guilty.
Update, 21:00: Corrected typos and clarified some points. You expect me to be coherent after hiking 20 km?
