There was police cars, guards, NYPD, ambulances and much more.
for the first hour or so we just went around looking at different stalls and also getting free stuff!:P Around half way through our wander we saw TangoBot. This was a robot made by NASA! T o be honest he was quite scary and liked to follow people around the place!
I think if people are just a bit more careful on the roads there doesn't have to be as much accidents on the roads!
All in all great day out!:)
