On the third day, have club leaders make presentations. Subdivide campers so assemblies are small and allow for questions and answers. Club leaders gather in a large tent or building. Each should have a sign and a large envelope bearing the name of their club. Give each camper a card with his name and group on it.
Campers enter the tent and deposit their card in the envelope of their club of choice.
Call groups in a different order for each sign-up rotation to ensure everyone gets a first choice at some point during the summer. Envelopes are then collected and sent the office to be recorded. Lists are generated by club and group so counselors and the office can easily access campers during the club period. These lists are adjusted for absent campers and any changes. The next day is the first regular day of club time.
