Gave a seminar in Uppsala today. The reward was a bit of dusk-verging-on-night-orienteering on Norra Lunsen. Re-ran a training I did with Paddy a couple of years ago. I wonder how hard that is to dig up.
Orienteering went well until towards the end when I wasn't concentrating so hard. It's pretty easy as long as you keep contact and know where you are going... although the skeletons may disagree...
