Send them home

I was the controller at an orienteering event at the Heriot Watt campus at Riccarton on Saturday. The planner put the majority of the controls out for the first race, and I checked they were in the correct place and 'awake' for the first competitor. As I went round the campus I saw this recycling  Ape Bank. What wits students are. The event was a success and people seemed to enjoy it.
