My office is Laurentide 2215, my Fall 2022 student office hours are Mondays, Tuesdays, Wednesdays, and Thursdays from 12:30pm until 1:45pm and by appointment. They may still be via webex. Yes, my office has both Packers and Broncos stuff in it. Here's why. I've also traveled to 5 continents, 16 countries (or maybe 15 or 17 depending on your interpretations of Falkland sovereignty and the Antarctic Treaty), and 38 US states (plus a district and a territory), as well as some land that's not part of any country.
