No, I still have your book "Charcoal Mushrooms" Camazotz.
As far as seasons go, there may or may not be a normal set of seasons, but worth investigating. However there would be in some areas more ideal or planting times, that would regulate those areas as seasons. Like the planting season, the growing season, or the harvest season. Summer being the growing season, would signified the end of the planting (spring) season and the end of the work that it details. Same as a harvest (fall) season would show the end of that detailed work, and getting the product to storage or market.
So,... in my view there would some resemblance of seasons, even if they were not actually [Spring, summer, fall,winter]
But! that's just me.
