A picnic on the go is always the best activity for the family on a day with great weather. Going outside promotes positive attitude and also gets the kids out of the house so they can get their energy out while running around in the grass with other children.
A site to see is the animals that coexist with us when we don't even know they are there half of the time. The squirrels are harvesting for winter and birds are building nests and tending to their new born babies so they do not go hungry. A picnic is a shared meal between loved ones.
