Made a trip to LA over spring break. On the way back I had one of those, H-m-m-m, I wonder .....
I pulled out the laptop and USB GPSr, put the GPSr in the window and put the shade down. There we were, flying over California at 35,500 feet. Streets and Trips didn't like the speed though! It showed the altitude correctly but the speed hovered around 56 mph. To bad they didn't have a power outlet, I'd have watched it all the way home! It was really fun to zoom all the way in!
