Chased the northern lights in Fairbanks Alaska! Temperature was in the negatives (Fahrenheit) when we looked for the lights but it was worth it! Stayed for 4 nights (3/19 -3/22) and got lucky we saw the lights every night, even from our Airbnb and the plane ride home! First picture is from a tour.
Also had the chance to go to the world ice championship (1st place pictured) and to the Chena hot springs.
