I'm not sure what option really fits me. I've never really flown in an airplane that wasn't IFR equipped and all of my night flying has been on cross countries in the rural midwest, a lot of people might call these areas sparsely populated and probably not well lit but if you're up to 5000' or better you can usually see at least one airport beacon and a few towns, albeit small so IDK if I'd really consider that a problem. Over some desert regions and open water that isn't going to be the case so for flying purposes that's what I think of when I think sparsely populated. Before I was instrument rated, I made many night VFR flights and I never really thought it was a big deal. My minimums for night where a lot higher- as some have mentioned you can't see the clouds so I flew on mostly clear or clear above 12,000 nights. I also had a rule that I only flew into airports I'd been to during the day and that had longer runways. Never had an issue doing this, I actually waited out questionable ceilings and scattered storms a number of times in favor of a clear starry sky night flight. Night air tends to be calmer/smoother, surface winds tend to be lower, and traffic is lesser and IMO easier to see. The scariest thing about it IMO is an engine failure when you can't see what's on the ground too well. I'm now IFR rated so if I fly at night I'm going to file IFR and not worry about the clouds as much and probably drop the only going to airports I've been to rule when I can fly an approach.
