This is not Promontory Summit, UT but it will do. To place a golden
spike at the midpoint of our journey was my idea. This is a simple
puzzle.
To find the Golden Spike you must first go North and visit "End
of the Line" then "Holy Diver", "South Jurassic Park" and "The
Moat" In that order.
Then go West and visit "Don't Give Me Lip" then"South Jurassic
Park", "Bridge to Nowhere" and "The Moat". In that order.
