Is it a bad idea to fly VFR at night and navigate by following highways? At
night outside large cities, there doesn't seem to be much else that's visible.
It seems to me that if you can clearly see the highway, it can guide you and
you can get a good idea of where you are with respect to terrain, so it should
work. Are there hidden dangers in this? Do night VFR pilots ever/often
navigate by following highways? What other forms of visual navigation are
usable at night?
