For most people, this is simply the last Monday of May. To Americans, today is Memorial Day - officially meant to remember those who died in service of the country, but unofficially the start of the summer season and a reason for people to get together, have barbecues and otherwise enjoy the long weekend and the (generally) good weather. Here in the Philadelphia Area, it's also the beginning of shore season, and thousands of familys flock to the Jersey Shore for their first time at the beach after a brutal, cold and snow winter.
