Urban Orienteering

I'm busy backblipping after spending much of today uploading 4000 photos from the Easter weekend. We have been in Scotland for the annual JK Orienteering Festival which always takes place at Easter but moves to a different location each year. The first day used to be for training purposes only, but in recent years with the rise in popularity of urban orienteering (I'm a big fan!) it has now become the first official day of competition. The urban sprint took place around a housing estate in Livingston which had lots of alleyways and courtyards, easy to confuse one for another. My blip shows a range of orienteers approaching one of the courtyard controls. I've just noticed that it has caused some debate on our orienteering forum because someone has mistaken the wall for uncrossable on the map!
