I have a slight headwind, so I don't hear the six 4WD vehicles sneaking up behind me on the Barnwell-Searchlight railway grade
I'm startled! I hear a noise, then notice six vehicles right behind me! Shocking, I haven't seen people in 3 days. As they pass, we chat briefly. One of them gives me a bottle of water (colder than mine, thanks!) and one of them thinks I'm nuts.
Some people don't realize it's possible and potentially rewarding to travel without a motor vehicle. Motor-vehicle advertising, which so many people happily consume, reinforces such ideas. Ironically, the people who think my bicycle trips are impossibly extreme are sometimes people much stronger than I.
