Listening to the It's the Little Things  podcast last night with Shawn Reilly on vision blocks in Louisville, I was struck by the weight of the observation that the cost of blocking small change in communities is that all you're going to be left with is big changes. We blithely accept restrictions on normal, small-stuff changes and then we can't figure out why all that seems to come up these days in our cities are massive developments of luxurious housing for non-residents.
