I was outside today chopping some bamboo in the front yard, when a weird-looking SUV bristling with cameras, antennas, and other electronic crap turned into our cul-de-sac. When it got down to the end and made the circle to go back out, I was able to see the stickers and logos emblazoned all over the sides -- it was one of the trucks from Mircrosoft Live Local Virtual Earth.
I wish I'd figured out what it was a bit sooner -- I smiled and waved and jumped up and down, but I'm pretty sure it was too late. They seemed like they were in a bit of a hurry. I guess I would be too if I were trying to gets shots of all the roads for the entire city of Houston (the entire country, the entire planet). Busy, busy guys.
