Strange how I used to be an "up all night" person. Might have been from all the swings I worked in the Air Force, and living for so many years in NV in towns like Vegas and Reno that never sleep.
But I don't care much for staying up at night anymore, the sun comes up, I can't stand being in bed. I'll be up at 5:30 soon as summer gets here and it starts getting light then too.
