Memorial Day marks the informal start of the summer and the busiest vacation and travel season of the year. Many Americans use the summer season to travel the U.S. to enjoy a wide range of recreational attractions and activities.
Summer is also the peak time for air pollution.
Smog and ozone endangers the health of all Americans, especially our children, elderly, and those with respiratory and immuno-deficiency illnesses. Automobiles are the primary source of air pollution. Fortunately, we can access and enjoy summer activities and help to protect the environment by using public transit and other alternate transportation to travel to beaches and other recreational attractions. Delaware's DART First State Resort Transit Service provides cheap, convenient bus service to its most popular beach resort locations. The Chicago Transit Authority's Summer Bike Access Program allows bicycles on trains during the weekend from Memorial Day through Labor Day.
