When I was younger they used to have a parade for Memorial day to honor those who gave the ultimate sacrafice..Kids would decorate and ride their bikes in it. Sad to think thats this doesnt happen anymore.
Host your own Fourth of July parade and let the kids decorate their bikes and scooters for the occasion. Supply them with pinwheels, ribbon, chenille stems, and more. If you're hosting a big crowd with lots of children, sponsor a decorating contest and offer prizes to participants.
