When I was younger and even more impatient than I am now, I use to leave for trips on Friday nights on a regular basis. Sometimes the hike wouldn't start until midnight. With much practice, I had little fear. Maybe not a good thing, but nothing bad has ever occurred, with the exception of losing where the tent was for a few hours one night after setting up and going for water. I got very use to trusting my balance and reading the shadows. I still do it occasionally, but my wife really does not like it. I use to hike in Death , Saline and Eureka Valleys at night and loved it. My wife and I have done a long night hike In Joshua Tree NP. I was challenged by a wild stallion one moonlit night east of Mono Lake. I never saw the band of mares, but they must have been in a nearby arroyo. Was I intimidated? I didn't stop shaking for an hour.
