Staff work as facilitators, not leading the group but rather helping the group lead itself and learn in the process.
While a ropes course is one way to offer these initiatives, we utilize "mobile props" such as balls, ropes, tarps, etc. to achieve similar results.
Participants can also find the inexpensive supplies and lead these activities with groups of their own. Initiatives are great for improving group dynamics without needing to commit to an outdoor trip or clinic which might scare away some would-be participants.
