@boomerang,
I'm interested. I haven't community gardened (since I had my own and designed others places thus was busy), but in my old neighborhood, spaces were precious in the cg place, and I think that is true for some places but not all. In some places they have been salvations, or touted as salvations - there are probably a zillion articles about that, or there were, and I'd guess it would depend on the energy of all participating
over time contrasted or working with neighborhood happenings. I've had a friend who worked with schools to set up gardens and associated info (she's a major cook and a keen landarch) and don't know if she is still whacking away at that as she's also an artist, but I think she stayed with it for a bunch of years.
Re getting kids to get interested and then shape up and graduate - or prison folk to find new or regained interests - I've read that gardens work, but my reading is from quite a while ago now.
So........ re the drawing, maybe it is true to life, beginners beginning.
