A new slideshow I put together on indoor adventures:

Once upon a time, doing extreme outdoor sports meant traveling far away from city life. There were no vending machines. When night came, it got dark. The terrain was laid out without a floor plan. There was something called “weather,” and the seasons determined what you did (that grass skiing thing never quite caught on). Now, for better or worse, those days are over. Humans have brought the outdoors inside, or they’ve simply recreated it outdoors, so your favorite adventure activity has an all-new, man-made, super convenient location.
