Field Trip Idea-Rockefeller Tower

My idea of a field trip is the Rockefeller Center. Rockefeller Tower is a feat in itself. Built by the the richest family known to man, The Rockefeller Family, the tower is a interesting feat of engineering and it has a garden on top of it. Look at it. Do you see this? It's just such a aesthetically appealing that it should at least be considered. I mean what other building will you see around NYC with a garden on top of the building? That itself is a engineering feat in its self. Considering it took nine years to build and it takes up 22 acres of land, there is no way to run out of things to admire. It also has an underground area full of resturants and shopping centers. There are many centers where great feats of engineering have been built, like the murals in the GE Building Lobby. It may just seem like an ordinary building, but it is in fact a great landmark that should at least be considered.
