California
I just heard a funny, but sad story on NPR’s Morning Edition: Neighbor A is suing Neighbor B because B’s Redwood trees cast shadows over A’s solar panels. In 1979, in the wake of the oil crisis, California passed a law guaranteeing the rights of people with solar panels on their houses. As a result, Neighbor A won in court (pending an appeal, natch), resulting in the court ordering Neighbor B to cut down 2 of 8 trees. I’m sure there’s some kind of pre-existing bad blood between the neighbors for it to escalate to this, but I’m still flabbergasted one California hippie would make another California hippie cut down a tree (the segment starts out pointing out how both neighbors consider themselves environmentalists).
