I live and work in a lovely college town. And where there are colleges.... there are LIBRARIES. Why didn't I think of this before?
Just when I thought I'd googled every variation of play, play deprivation, playwork (very few results by the way), playgrounds and "are we all going to rot and become robots for lack of spontaneity, and joie de vivre...?" I found my library. And oh what a good one it is. This is just the beginning.
