Rain, snow and sleet can't stop true sports fans. When the clouds roll in, head to an indoor sports arena in your area. Many of these complexes feature batting cages, swimming pools, basketball courts, ultimate Frisbee fields and other places to stretch your legs.
To create a little friendly competition, divide your family into teams and compete for silly prizes. As you race from one event to the next, you'll get the heart pumping and the blood racing. If this event is a hit, invite other families to join in the fun.
