Each Lodge was given a map and a list of simple grid references. The principals of working out where a grid reference related to were explained to them. Then with their adult “minders” they were advised to plot the references and work out a route that covered each point. These were all in Longford Park. Then wearing high vis vests they set out to answer the questions. Most Lodges managed to find all the answers but Thrush Lodge were the first back with all the right answers.
