Question of the Day: Indoors or Outdoors?

Since we’ve already been through WHEN? and WHY? I guess we’ll continue our questions with…WHERE? Do you prefer walking indoors or outdoors?
We’ve had some ridiculous weather this month. We’ve had more snowy days than I can remember having in years. We’ve had days where the high temperatures were in the single digits. We’ve had weeks where the temperatures never rose above freezing. In short, it’s been COLD. When it’s that cold, I stay indoors – on the treadmill or at the mall or some other indoor option. Overall, though, I definitely prefer walking outside – even if it means adding a few extra layers.
What about you?
