I work at one of the hotels on the strip (same place for 24 years, now). I got up at 4am and I was driving to work. I turned on the radio and they were talking about a mass shooting. My first thought was, "what state did this happen in?" Then I heard the details. Truly sad. My hotel is 2 miles from Mandalay Bay. No problems getting in.
I had a long shift, so I just got home and still haven't turned on the TV, but I'm about to. My prayers go out to those affected.
