A thing I really enjoy is apparently tours of factories. One of my favorite days at NYU was visiting our printing press, and I was really excited when I had the opportunity to take a tour of Dartmouth's steam tunnel and power plant a few weeks ago.
The tour was led by William Riehl, chief operating engineer, and I learned a ton about how Dartmouth supplies energy to all the different buildings on campus. I also learned that in steam plants like this, most of the employees come from the navy, where they use very similar types of technology on the boats.
Bill was very informative, and it was great to see a part of campus I would never otherwise have seen!
