I just returned to town after spending my second night in Arizona's little-known Pinaleno Mountains. I am here for work, but chose to take advantage of being near these gorgeous mountains. The Airstream stayed in Phoenix. I have been truck camping, sleeping under the stars in the bed of my pickup.
As mentioned a couple of years back, I wrote an article on these mountains which is mostly unchanged and available right here on Wikipedia.
I stayed at lower elevations to avoid freezing mornings. I wish I had a week to just explore and be outside. The highest point of the Pinalenos is almost 11,000 feet above sea level.
What a joy to be camped out on the edges of one of Arizona's islands in the sky.
To get a full appreciation for the island reference, go to the Wikipedia article.
