The truth is an outdoor classroom doesn't have to be elaborate or glamorous
, it might simply be a sheltered pavilion or an outdoor picnic bench. The point is to create a space where people can comfortably learn. Of course it's best to be in a location that is fertile and has a lot of natural life around it, that way learning through observation is possible. When you decide the time is right to expand, think of it as a way to develop and better the existing ecosystem.
