Defining a plan of action for this subject is simply to hypothetical at this stage, as I'm unaware of what's possible/desirable to do. Rest assured that it is not a problem to continue a participatory, hands-on and theoretical course also without being outside and constructing something new. Potentially a construction could be made in parts during the winter and moved out  in public space during the spring?

One suggestion I do have for SJH (After studying your site) is to construct a very appealing natural mobile sales booth to be temporary mounted on a trailer when you go to the farmers markets...
