Easy hike up to the crest of Necessity Hill. There’s no marked trail to the top, but there is a little dirt lane with a sign “Authorized Personnel Only.” (Peak-baggers are authorized, right?) A very young George Washington had to construct a hasty makeshift fort on this hill in 1754—“Fort Necessity.” He had just ambushed and murdered a band of sleeping French soldiers nearby, thus bringing the so-called “Seven Years War” to America, where it’s typically called the French and Indian War. No views from the top, but a pleasant climb.
