a bicycle can be fun, can be social and can be scenic. Cycling is
also a recreation that can bring better health and an improved environment.
Cycling provides exercise that is good for all bicyclists regardless
of age; and it doesn't pound leg joints like running does. The exercise
has value whether the pedaling is slow and casual or fast and aerobic.
Using a bicycle for an errand, a trip to school or work, or a visit
to a friend saves an auto trip. That means less traffic congestion,
pollution and greenhouse gases spewed into the air.
