@peterme@notjustbikes@fuckcars Thinking of books that can set a foundation. Jane Jacobs is good and would likely be good for a 15 year old, but I always think of her work as an incredibly good counter weight, but not a starting place.
Understanding scale, how cities work, the why of cities, and the impact of cities on their people I think of as good foundations.
