The park is undergoing extensive renovation and many areas are blocked off, including the bridge leading to the gazebo ( you can still get to the gazebo by another way) and the set of stairs likely referred to in the clue. Quel dommage!

We searched extensively, but unfortunately we couldn't find the box.
The park was lovely even in the rain.

This is a really unique park! Amazing to think that it was all created by people. Really cool. My camera really helped to disguise what I was up to as I sought this box. Just call me the photographer who sticks her head into bushes to get shots. As a decoy, I did this with many of the bushes around the area (b/c there were some people just hanging around up there). It amused me! :-)
