Update 2/24
Things didn't go exactly as planned today, but all has worked out well so far. We got a late start from Blythe (telling people in the restaurant about our trip), then we lost an hour because we entered the Mountain Time Zone, and we had our first tire "incident" (a blow-out). Bottom line: not enough time to make it to Salome, as we had planned. So when it started to get late, we concluded that 42 miles was enough for the day and decided to stay in Brenda, about 25 miles short of our planned overnight.
At the local General Store, we began to ask if there were any RV parks that would accept tents, and it looked promising. Then one of the ladies we had asked came riding back on her ATV and told us she had found us a place; it turned out to be a 45-ft RV. Now isn't that an upgrade from our pup-tent! Talking about plush!
This will probably cause a change in our routing. We'll have to make the decision tomorrow, based on the time we depart, but we'll likely cancel the ride on US60 to Salome and instead go directly from Brenda to Tonopah via I10.
Another beautiful day: dry, clear, and high in the upper 70s.
