I ride late at night quite often... In my opinion it's my favorite time to ride, especially when I basically have the roads to myself. The amusing part is the look on people's faces when they see me out riding around having a blast... Not that I care, I absolutely love it. The only thing that's lame about nighttime in TN is the fact that the humidity is always 90-95% at 70 degrees. I sweat like crazy even though the sun isn't even out.
