According to City Councilman Mike Laster of District J on the southwest side, the biggest problem with stolen shopping carts taken from local retail stores is that they often wind up tangled together at the bottom of drainage canals, effectively forming giant dams, blocking water flow.
Things get bad when Houston floods. Water swamps homes, takes lives and shuts down the city. But it should be so much worse. There shouldn't even be a city here. But there is, and most Houstonians casually accept the enormous drainage system - the bayous, creeks and gullies - that keep it precariously dry in a former wetland.
