Walking, cities, and baseline fitness

 Growing up in Marietta, Georgia, I played outside quite a bit, but while our neighborhood had some nice creeks and forests, it did not have any sidewalks. When you went somewhere, you got there in a car, even if it was less than a mile away. I remember driving to Eastside Baptist Church, which Google Maps says is .07 miles away from my childhood home. Walking was for the mall.
