The 1919 PGA Championship was the second PGA Championship, which is now considered one of golf's major championships. It was held September 16–20 at the Engineers Country Club in Roslyn Harbor, New York, east of New York City on Long Island in Nassau County.
The first PGA Championship was also held in New York.
There were no facts in the statement to back up my statement.  I think this is why it is also hard.
