In the middle of the winter, when Northern Lights can be best appreciated, fly up to Saariselkä or a similar Finnish resort above the Arctic Circle, check into a good hotel, rent a pair of snow-shoes, wait for a clear night when the Lights are most spectacular, walk out into the snow, and head north. Walk as far as you can, making sure you do not unwittingly end up back at your hotel. If you are lucky, it will take years before you are found.
