An airport isn’t the worst place to find yourself with time on your hands. Especially when there is an observatory available, and you decide to wander to get your steps in and also see what the sunset brings.
The observatory had angled windows which quickly became my obsession. Until I looked up and saw that a plane was flying across the sun, but I didn’t have time to get that photo. So I alternated between looking for the sunset reflections and waiting for planes to take off toward the sunset. And there was a little bit of Christmas too!
