Was this an interview? You might be able to use the extra time to tour the town, weather permitting. If it was a talk, is there someone at the university that you've been working with? You could always get together and hash out some ideas. And if those two ideas don't work, there's always the hotel bar!
Just a talk, not an interview. (I am gainfully and happily employed on the tt.) The weather would indeed make touring the town unpleasant, but I will certainly contact the people I was visiting if need be.
