My office is Laurentide 2215, my Summer 2024 student office hours are by appointment. They may still be via webex. Fall 2024 hours are still to be determined. 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.
