Memorial Day started in 1868 after the Civil War ended.  Dead soldiers from both the north and the south were honored as a way to try to heal the nation.  Now all past soldiers are honored.  It is also a day that is considered to be the start of the summer season.  Many people celebrate with a cook-out or even a trip to the beach.  Many towns have a Memorial Day parade – this would be fun to watch, or even to march in.
