13. You can tell where you are from the lamp posts
If you’re ever lost and you dropped your phone in Bethesda Fountain, there are 1,600 lampposts throughout the park with numbers on them that correspond to where you are in the park. For example, if you see 8316 on the post, that means you’re near 83rd st on the East side -- the first number tells you the closest street and the second tells you how far East or West you are with even numbers representing distances East, and odd numbers representing West.
14. The biggest concert in the park had 980,000 people in attendance
That sounds impossible to us, but apparently those are the official Fire Department numbers for the Garth Brooks show in 1997. The Simon & Garfunkel show was reported at 500k, too, which is not too shabby.
