My route to work include a bike path and the tow-path at the D&R canal near Princeton. It's a 30 minute ride to Princeton University Dillon's Gym. Princeton University is quite bike-friendly and having the bike at work helps with transportation within the University.
I work at Princeton University and commute to work, mostly for the exercise. I also enjoy the beautiful views of Lake Carnegie and the D&R canal in the mist of the morning.
I got a hybrid bike (Gary Fisher Fast City) to commute. It was the best decision I made. That bike is light and fast, even with the panniers, lights, etc.
