To me, Labor Day was completely significant to the end of summer, a reason for a parade, and a typically great time of year to have a cook-out. Also, many people say you should NOT wear white after Labor Day!
Another thing I associate with Labor Day is that there are more accidents that are caused because of drinking and driving, and people try to take long weekend trips and speed to make better time. This is always a sad occurrence that seems to be shared on the news year after year.
I know that there had to be more to Labor Day than that, so I decided to take a few minutes to actually learn about what Labor Day should mean to us as Americans.
Here is the Wikipedia definition I found:
Labor Day is an American federal holiday observed on the first Monday in September (September 3 in 2012) that celebrates the economic and social contributions of workers.
Labor Day pays tribute to the contributions and achievements of American workers. It also symbolizes the end of summer for many Americans, and is celebrated with parties, parades and athletic events.
