Indy, I feel the same way, actually. Being outdoors riding or running, or doing winter stuff fills my need to be in nature and my need to exercise. That's why if I am short on time, I would rather walk the 2.2 mile loop in my neighborhood, where I can see nature and get my HR up going up the hill. In fact, I originally started mountain biking because I love being in the woods, since I was a kid, in fact. But, the actual mountain biking part didn't work out so well for me, so now hiking is my alternate activity in the woods, during warmer weather.
