I used to live in McKinney, Texas. A friend who also lived in McKinney owned a small airplane and for years he frequently flew to Austin to visit his parents.
Then George W. Bush declared his Texas ranch his Western White House. That didn’t affect very many people, but it affected my friend.
When he flew down to see his parents and then President Bush made an unannounced visit to his Texas Ranch the air space around the Waco/Austin area was closed and my friend had to catch a bus back to McKinney and return for his airplane after the president went back to Washington.
If Donald Trump decides to commute from his New York home to the White House each morning and then commute back to New York each evening, as he is considering, I wonder how that will affect air traffic around the NYC/DC area?
