With the NFL Draft just 2 days away, there's plenty to see at Union Station now (except the station itself which is hidden behind all the scaffolding). I was able to get inside to see the lobby that has been transformed to the Green Room for the draftees. I had to peek where I wasn't supposed to but ... you can see the back side doesn't show you anything.Signage is everywhere now where there was none last time I visited. 
With all the street closures and fencing I was expecting to see something momentous in preparation for the NFL Draft. But so far a basic roof frame on Union Station and a stage on the World War I Museum grounds is it. But they have made it quite hard to get to Liberty Memorial to take a photo.
