In patrols or groups of 4 or more. Each group explores the local area finding items, names, or signs that refer to a letter of the alphabet.
Each group starts with 26 points. You lose a point for ever letter of the alphabet that is not covered or any item that is the same as another group's choice of item. Also losing a point for every minute late they are back to the meeting place.
If they have all the letters of the alphabet covered they also gain a point for ever 5 minutes under the time they are.
