I fly SEL at night (in IMC as well) because sometimes my schedule
demands it. It's also often really beautiful at night: moonlit
landscapes or cloud tops are wonderful, and it's rarely so dark there's
no view. FWIW, however, it's the unusual case for me to fly at night
under VFR. I almost always file an IFR flight plan (but do that in the
daytime, too: it's much easier getting into busy airports that way).

Then there's this: those with an instrument rating will understand.
Sometimes the ceiling is flat and just above minimums with good
visibility below. There's nothing quite as exciting to be in the clouds
at night, break out at 200 feet and have the runway and lead in lights
right there, right where they should be. A half mile at an average
speed of say 80 means you go from solid instruments to in the flare in
20 seconds. The best word I can think of for that experience is "neat!"
