Thanks to the Courier for publishing my story about a onetime MASSIVE structure in what was to become Riverside Park, made to enjoy a sport that was just catching on in 1886-7. I had never heard of this item before, and it seems to have been a flash in the pan that vanished almost immediately from the scene. Still researching what happened to the structure. So far all I've found is that it was partially damaged in a big flood in the spring of 1887--in fact, the bottom part was partially washed away but prevented from doing so by the trees in the park. I'll definitely publish an update when I find out what happened to the vision of these five young dreamers.
