Jack went to a birthday party for Anton at Laser Force. Afterwards, we worked cleaning up the yard and the garage at the rental and then took groceries to Sharon's parents.
A couple of weeks ago, I heard about a Nova broadcast of The Great Robot Race on a CNET podcast. DARPA's Grand Challenge featured driverless vehicles competing in a 130 mile race across the Mojave Desert. I had tivo'ed the show and we watched it after dinner.
