Extra Credit

On my trip in October, I went to the Empire State building.
 It was the tallest building at the time it was built.

At the time, a popular way of tranportation was by zeppelins, or balloons. The mast was designed for the zeppelin to moor. However, it was never used.
 This is the view from the top of the Empire state building. We could see the Verrazano-Narrows Bridge which was the longest suspension bridge at the time of its compeletion in 1964.
We saw the Brooklyn Bridge while we were in New York.  It was the first bridge to use steel cables when it was built in 1883.

We also visited my granddad in North Carolina. We talked about his former job, which was a metrologist. They make sure that the measurements and physical qualities are correct for buildings.
