I enjoy passing the time on airplanes with my phone held up near the window to get a GPS signal, and then look at the names of towns and landscape features far below as I pass them by. It is quite surprising how anything you can see tends to be 10-20 miles off to the side of the plane, until you start paying attention to the quantity of 1 mile cropland squares. Then you truly appreciate how high you are! This takes 100-300MB per state--I use OsmAnd via F-Droid of course.
