changed in a few hours.
considering the poor weather, i was pleased with the good scores. when i was putting out the controls, i was thinking that the map area too big, but from your comments, i now think it was just about right.
thanks again to everyone who gave me support with the planning, maps and collecting the controls.
from the positive comments, feedback i have received it makes me look forward to planning a future event so i would like to say thanks to you all for a great day.
