Come on guys/gals. Tell us!

I'm one of those people who is out riding my bike in the heat, the cold, the wind, the biting insects, the dust and grit, the rain and the sleet. I would love to be content to get my riding done in a nice, indoor, climate controlled fitness center with big flatscreen TVs and pretty attendants. But nooooo... I can't stand the boredom. I seem to be programmed to need the changing scenery, the exploration, and the adventure.

How on Earth do you make yourselves happy sitting on a trainer inside a gym?
