Query: Essential reading for any urban planner.

This book is terrific because William Whyte doesn't relie on any theory. Instead, he logged countless hours watching street corners, public parks and plazas to see how people actually use them, and draws conclusions on how to make them better, safer, and useable. His ideas of planning public areas were first used to a great extent in redeveloping Bryant Park in NYC. Formally a haven for drug users, the city used his findings from this book and turned it into one of the city's most livable and exciting public areas. If only we could design all our streets and plazas with such good common sense!
