I was there. First time being on the arch grounds for the celebration. Opted to park at Grand and 7 of us used Metro to get downtown. One of my friends had a guest in town from Brazil. Have to say it was a very cool, very "big city" experience. Metro was packed, and the arch grounds were packed. Must have been hundreds of thousands there. The drones are very cool. It is amazing what they can do today. Can't go this evening, but if you have never been I would suggest checking it out.
