I know two people who collect rainwater into barrels, for chlorine-free watering of their gardens. A storm like yesterday's easily fills three barrels off an ordinary roof. Unfortunately, the city isn't building many ordinary rooves over ordinary homes on ordinary lots anymore. Nor is it patching concrete as adroitly as it used to, as I saw on this patch of Hope Street between Eleventh and Twelfth yesterday. Still, where civic structure fails, culture often takes over. This will be a busy week--excuse me.
