While waiting for the fireworks show, I noticed a couple of 'new' pieces of equipment. Both are in the north west corner of the hub.
First there is a condenser hidden in the flower bed. Before someone posts it, I'm pretty sure it's not for keeping uncle walt frozen. What else could need cooling in the hub?
I also noticed some big green square things. They are about two feet cubed. I think those could be new speaker/subwoofer enclosures for the show?
Finally take a look up on the light pole in the area. In between the parade lights, there is a clear dome. It looks like an electric meter. Any clues?
