Have we changed the way we picnic? I recently watched an old Mad Men episode where the Draper family drives out into the country for a picnic lunch. The scene is exactly what you expect with a wicker hamper and a blanket. As they pack up to go home, Don tosses his empty beer can into the bushes and Betty flings the paper napkins and plates onto the grass, which made the internet really sad because no one likes a litterbug. But aside from the littering, has the art of eating on the grass changed?
