We must associate Camper with Session independently of the camper's Unit, because not all Campers are assigned to Units, and we still need to know which Session such a Camper is attending. We have a many to many with history between Rotation and Activity. An Activity can be scheduled during many Rotations; and many Activities can be scheduled during each Rotation. It is with history so we can have the same Activity scheduled during the same Rotation more than once; perhaps there is more than one Archery station, for example, and two Units can participate at separate Archery stations. There is no penalty in the rubric for doing this association without history, however.
