Kat and I are back from a short trip to Boston, a mix of business and pleasure. I participated in a panel discussion Wednesday at the Silicon Valley Bank in Newton on carrier IP security and met with a customer on Thursday, but most of the rest of the time was available for sightseeing. The photos are from the Museum of Science and the Charlestown Navy Yard (where the U.S.S. Constitution is docked), respectively. We walked the Freedom Trail, saw numerous art cows, and spent some time with friends. We came back before the big Boston Pops concert/fireworks show on the Charles River, but we did get to see the fully-loaded fireworks barge being pushed into place.
