Last year I went to visit my sister in Tucson, AZ.  I had never been to the desert before.  My first hike was a solo trip into Saguaro National Park on the Sendero Esperanza trail.  The terrain seemed extraterrestrial.  I meandered from flora to fauna, paying close attention to this new world. I moved slow in the heat. I saw birds fly in and out of holes in giant cacti.  Lizards sprinted across the trail. The ground was red, covered with beautiful, sharp rocks.  Everything I passed had spikes on its ends.  The sun was unavoidable. I enjoyed the desert very much!
