That almost divides perfectly into 24 time zones of 1,000 miles each. Allow for a smaller circle around the earth at our northern latitude, and maybe we’ve got 750 miles in a time zone. At our current pace of 250 miles a day, Judy and I should cross into a new time zone about once every three days. Since Arizona doesn’t observe daylight savings, we were effectively in the Pacific daylight time zone when we were there. When we drove out of Arizona into New Mexico, we stayed in the same time zone, but now observed daylight savings time. We turned the clocks forward an hour.

And we accomplished it in only two… Meanwhile, we continue to head east and south in search of humidity. return trip map We arrived at Balmorhea to 91 degrees and 5% humidity. That’s a little dry for us. We have the humidifier blowing full blast in an attempt to make the air habitable. We’ve got it up to 16 percent so far.
