Years ago we went to an Orioles game at Camden Yards on opening day. President Clinton was there and threw the first pitch. At the beginning of the 6th inning the guy next to me got up to get hot dogs. When he came back more than half an hour later I asked him why it took so long. He said the president was leaving and they shut down part of the stadium while he was being moved. He was trapped for half an hour at the hot dog counter. It seems the president has to leave games early for logistical and security reasons.
