I get to spend about 40 minutes a day there when I walk to the shuttle and back. And I try to walk to a different part of campus at least once a week. I'm involved in a program at work where I'm trying to walk at least 175 minutes a week. Four shuttle rides a week is 160 minutes, so I just need to find another 15 somewhere.
The weather's getting nice, so it's easy to spend time outside now. Maybe it's time to bring the bike in for a tune-up.
