Day 20 of Thirty Days 2013 was the calm before the storm in the Denver area. Tomorrow a cold front with some snow is expected to drop temperatures and a little snow in the metro area. As I mentioned yesterday there is change happening around Union Station and in this image you can see some of that change. Earlier this year I posted an image from roughly the same spot with the Davita Building included. Now there is a building in the background and a crane in the front of this building. In the next couple of years the skyline will change in this area and it will be interesting to watch it develop.
