Orienteering 20:00 
turning on controls loop. my plan was to turn on all the controls that the early starters weren't going to get to. the route took me through a bunch of controls, then to the start to do a final check, then out onto the hill. I made as far as the start where I stumbled into the great control description crisis. I guess it was lucky that they were sufficiently wrong that the early starters had picked it up. and I had my laptop with the latest course version in the car. we had an hour then till first starts and decided to prioritise the elite courses and the moderate courses. not ideal, but better than a lot of cancelled courses.
the main lesson for the day was how ineffective "checking" anything is once you've reached a certainly level of stress and tiredness.
the other was that 99% of people are lovely and understanding and appreciate that sometimes not everything works out perfectly.
