I fly using the X-Plane Flight Simulator. It has an actual entire planet Earth scenery and topography in it. It’s not quite as good as or as detailed as Google Earth, but it’s good enough.
I hop from place to place, recording the entire flight. Later I create a short highlights video, put it on YouTube and post it here along with information about the flight. I also “visit” the places I land at, by usually looking at a YouTube video or two that someone who has been there made. I’ll also read Wikipedia page about the place (at least) and a few other pages. I’ll also make a blog entry about the places I visit.
Several places are also part of some major themes, for which I might read a book or watch a documentary or a movie. For example Russian expansion into Far East, or how did Europe colonize Africa. Those are also listed here. also here
