Grand Central Terminal this was one of the most educational trips ever. We had such an exclusive tour that tourist would beg to see. Just the fact we had the chance to walk the glass catwalk was breathtaking. There was no other shot more unique than taking a shot from a tiny little window from the highest floor on the glass sky walk. And we still got to see the UN building from the terminal too. Overall this tour was so worth going and never again will I get the exclusive tour like this.
