Night flying is a lot of fun in several respects. First of all, it is a unique piloting challenge. Even when flying a familiar model at a familiar place, doing so at night gives the experience a whole new feel. You don't even have to fly to enjoy it. Watching the lights and shapes move around the sky provides the same kinds of "oohs and "aahs" as a fireworks display (but hopefully with fewer explosions). For you photography buffs, night flying offers really great opportunities to capture colorful and unique long-exposure shots.
