What is the happiest place on earth? Well, if you're a dog, it's probably the City of SeaTac's Grandview Off-Leash Dog Park in Seattle Southside. Grandview has 37 fenced acres of walking trails, forest paths, agility courses and open fields for play, and, of course, the namesake, the grand view. But while you're enjoying a sprint, sniff, shake, or catch with your Fido, Kingsley, or Emmylou, what you might not know is what actually happened here at Grandview nearly 60 years ago, or more accurately, what didn't happen here at Grandview. Because here in the 1950s and 60s, this delightful spot was anything but the happiest place on earth. Here Ajax, Zeus, and Hercules weren't just great dog names borrowed from the gods, they were supersonic missile-based air defense systems designed as a last line of defense to bring down overflying Soviet bombers during the years when humankind came closer than any other time to nuclear incineration and in which the United States and the Soviet Union began the greatest arms race in history. And today's Grandview Off-Leash Dog Park, here in Seattle Southside, was project Nike Missile Launch site S-43. Grandview got the Nike Ajax missiles in 1954, one of 11 Nike sites forming a defense ring around Puget Sound. Here Site S-43 could launch 30 missiles, each with a 30-mile range carrying three high-yield explosive warheads ready 24/7.
