To manage the threat still posed by Covid-19 variants, we are employing additional measures. We require vaccination against Covid-19 as a condition of participation. We ask that all participants take a rapid Covid test the day before beginning our program. In addition, we have increased adult supervision, increased rooming spaces, heightened daily health and wellness monitoring, revised illness response and virus mitigation protocol, mandatory vaccination policies and, where appropriate, indoor masking requirements for all participants. In the field, we have structured itineraries to maximize the outdoor, open air activities, minimizing time spent in close, non-ventilated spaces.
