Plein air sketch of some cranes at the historic Mare Island shipyards. This  former Navy shipyard dates to before the Civil War. Submarines were the last ships built here. One of the sobering facts I learned was that one of the atomic bombs, Little Boy, was loaded on a ship here and transported to Tinian Island to be loaded on a B-29 Bomber.
