This cache is the one that started it all for me. I found it using a new app with WiFi on an Apple iPod Touch!! I maintained the original secretly for the owner that was not reachable. It was finally archived during the new arena constuction. I hope you enjoy it as much as I remember enjoying it myself.

Here is the original description:
As a kid in the '70's, I remember playing in this "concrete jungle" just outside the store on K Street mall. There was a concrete snake you could slide down and other concrete animals to climb on. There was even a river running through the jungle. But sometime later, all that concrete was deemed too ugly and replaced by a modern shopping mall. If you have memories or photos of those concrete times, please share.
The cache should be easy to find once you get the right VIEW.
