Urban waterfall

Up here in "Little Dominica" they're big on opening fire hydrants. One particularly hot day I counted 4 open hydrants in a 6 block range. Seems at least one person on each block has the special wrench to open these things. Sooner or later the fire department shows up, shuts the water off and 20 minutes later it's back on and the kids are back in the street enjoying their own little "urban waterfall".
