E.E. "Doc" Smith wrote the Lensman series of novels. They set the mold for what became the Space Opera genre. If you want to read a copy, it is on Project Gutenberg as a free eBook.
This new series of caches is themed around some of the great science fiction novels. It will take you along an extension of the Alpine Trail in Portola Valley.
Please replace as found and beware of muggles. This trail can be quite busy at times. Cycling and hiking the trail are good choices. Parking near the alternative Dish entry is not a bad place for this one.
