I haven't been back to Flushing Meadows since I went to the World's Fair in 1964 with my dad and sister. Wouldn't it be cool if someone mapped it so my second visit there could be for orienteering!
But I have vicariously revisited that area, and specifically the Unisphere, via the Flight of the Conchords"
("New Zealand's fourth most popular folk-parody duo").
If you want to get in a bit of orienteering in that part of NYC, there's no need to wait for a Flushing Meadows map to be made. There's an event a month from now at Randalls Island
