from what I am hearing, it seems they have a plan to test everyone a few days before (assuming we have widely accessible rapid testing by then), and then lock the camp once everyone in side. Granted there is risk of an outbreak, and camps are ill equipped to deal with one, however the idea of sleepover camps seems more feasible and controllable than day camps. Additionally, assuming no immunocompromised kids, the camp population is extremely low risk, though you would have to make a judgement on Head Staff.
