For the people who are wondering whether this is a good idea or not, lemme tell you about some x-country cyclists I met on a ride. 3 years ago in the middle of summer I was climbing Iron Springs Rd on the west side of Prescott AZ. 3 youngish cyclists were paused on the side of the road with an apparent mechanical. They had a modest amount of camping gear in their panniers. Turns out they were French, had the barest grasp of English (I have the barest grasp of French), and needed a derailleur adjusted (no gears, no climb). I fixed them up and of course I was damned curious about their situation. Turns out, they on a whim flew into NYC, bought some not serious bikes and camping gear, and... just started biking across the country! In the middle of summer! In the wrong direction! Going to LA! And their pins... NOT CYCLISTS.

The Iron Springs climb tops out at 6000' or so, the weather is awesome in summer. However that is the end of weather happiness for 300 miles or so, because it's a steady drop from there into the desert, all the way down to the Colorado River. Temps in the 100-115F range are normal. Water is scarcer there than on just about any roads in the country. I was pretty alarmed so I got it across that they needed to show me their route. As best I could I showed them the best way on maps to not die. I tried my damnedest to get across they should not bike in the afternoons. "extra chaud!" etc.

And off they went. Never found out if they made it or not, but... you just can't keep humans down. They will always find a way to do the craziest things.
