Many of us, me included, need some purpose to our walking. I have kept myself busy for an additional ten years after I was already bored with walking in Oslo by using the handbook for “Kjentmannsmerket“. What to do next? The obvious answer is of course Geocaching which has become extremely popular the last few years. There is also another less known (and more geeky) answer: Playing Ingress. I have not started on this myself (at least not yet), but it is a possibility to get your @ss moving and at least get to know your own home town better.
