Yes...I neglected the fact that it depends on where you are on the globe 
as to your opportunity for high elevation passes.

I just saw one the other nite that came in from about 15 degrrees and 
was directly in line with the approaching airline pattern landing 
queue.  It was WAY brighter than the headlights on the planes--I was 
very vocal about how bright it was--even XYL was impressed ;)  ( tho she 
thought we weren't too bright for being out there in the 18 degree night 
looking up in the sky)
