not really sure this is true. With the map scale set at 10 miles, I can see several places where the walk would be a hundred miles to I80. And not an easy 100 mile walk at that.That same type of incident alone in your own driveway or yard would likely be fatal alone. While the pony express trail is 550 miles long, I really don't envision a spot where you'd be 100's of miles from anything, I-80 basically runs the same route. Just because people choose to run the trail that entire distance doesn't mean you couldn't take a left or right and be at a freeway within minutes. Yes the worst case scenario could happen and kill you on the trail, but that could also happen at work, in the home, or on the freeway. Calculated risk. And the freezing rain would fall into weather extremes where we don't go out alone.
