I think it was February 2016 or 2017? It was when I was thinking of going back to school in Estonia/Finland (it's extremely cheap) but wasn't sure if I could handle the winter. When I went they had billboards at the airport like "you've come to Finland in the winter you're a badass!"

It was also when the high school seniors have their study break so the whole week we were there had teenagers all dressed up crazy making parades through the town to go to parties. It was really fun to see!
