I think so far, getting to study the Northern lights in Svalbard!
I had to do special arctic survival course. This is so I could survive living in such a cold place! It also taught me how to deal with polar bears if I ever saw one 🙂
I did get to see polar bear, but it was really far away. It ended up getting too close to the town, so they tranquillised it and flew it back to a safe place away from the town.
