Was recently in Raleigh,NC where I was forced off the Fletcher Park Path by a Mommy Armada. The sweating mamas were jogging with junior who was, in most cases, sucking a pacifier or snoozing. The mamas had matching teeshirts with perky slogans and a few black Labs.They had marathon grade strollers with swiveling front wheels. At first I wondered if this could be considered PIE exercise as opposed to the more artificial forms of non-integrated exercise.I decided it was PIE. The mamas were getting an exercise unit while junior was treated to a glimpse of the outside world, albeit a fast glimpse.
