Nike Missile Site SF-88
The only fully restored site of its kind in the United States, the museum at SF-88 provides a firsthand view of menacing Cold War–era Hercules and Ajax missiles and missile-tracking radar, the country's last line of defense against Soviet nuclear bombers. It's worth timing your visit to take the guided tour, which features period uniforms and vehicles and includes a visit to the missile-launching bunker. On the first Saturday of the month the site holds an open house during which Nike veterans describe their experiences.
