I had a little downtime in Las Vegas between two trade shows so I decided to spend it out in the middle of no where.  Boy was I pleasantly surprised!  Initially I was thinking it was going to simply be a half day trip.  I stayed the whole day.  Unfortunately they boot you from the park right at sunset unless you were camping.  I wasn’t, so I stretched things as long as I could before the rangers got angry.  It is well worth the time and the trip if you are ever in Las Vegas.
