flying: when you get above that first level of cloud cover, and discover that there is a whole different weather/light situation going on that you had no idea about.
Case-in-point: these were taken somewhere between Atlanta and Raleigh-Durham. We had some turbulence taking off due to the rain, and it was already dark outside. But then we broke through the cloud cover, and were treated to a peaceful, aerial sunset that the Earth-bound weren't able to appreciate. It went well with my Biscoff.
