I Love Chicago!: I stopped by again last night, cache in hand, but the construction is still going on and there are fences in place.
I did thoroughly check out the 3 approaches to the island and while the northeast and south are completely blocked, I was able to access the hiding spot from the northwest as there was a gap in the fence that has been well used by fishermen and the homeless.
Decided not to put the cache into play as there is still considerable landscaping being done. The old hiding spot is doing well.
Hopefully this cache might be a candidate for unarchiving when the work is done.
Either way the cache will be back.
Stay tuned...
