Weekend Warriors

Ask your middle-class or wealthy friends with children between the ages of eight and 18 to do something fun on a weekend in the spring or fall. I would bet that at least half of them are busy, off in some exurban wasteland, logging in to apps like TeamSnap and SportsEngine and GameChanger as they shuttle their kids back and forth between a $200-a-night room at the Marriott, a Chipotle, and a sports field.
