Oskar and Dad went for a night camping behind the barn at a ranch about 30 miles away, then next day a spot of fishing at Lake Del Valle on the way back. A very pretty wooded valley lake created by a 1960's dam (of course, part of the CA State Water Project - one of the last great public investments in CA), just 5 miles south of Lawrence Livermore National Laboratory - yes that laboratory where almost all Cold War nuclear warheads were developed.
