Compare Indoor and Outdoor Versions of Your Favourite Activity

You do your favourite activity in one setting and never really question it. This works through what the other version would give you and take away, across fitness, skill, safety and access. Good if you run on the treadmill all winter and wonder what you lose. You come out knowing which one fits where you are.
