My office is Laurentide 2215, my Spring 2025 student office hours are 9:30am-10:45am Wednesdays; 12:30pm-1:45pm Mondays, Tuesdays, and Thursdays; 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, between 20 and 24 countries (depending on how you count the Falklands [Argentina/UK], Antarctica, and Aruba [separate from the Netherlands or not] - 21 is probably the right number (counting the US), and 39 US states (plus a district and a territory), as well as some land that's not part of any country.
