Suggestions for visit to Binghamton?

DS and I are going for a 2nd look this weekend. We are driving up Fri night & touring Sat. Any suggestions on what to see/do while there? He was accepted and now visiting his top 3 schools. DH visited with him the first time so it’s new to me, but if there are any points of interest on campus (maybe that aren’t on the tour?) or off campus, I would love to know so we can make the most of our trip. Thanks!
