At first sight , maple heights , just outside cleveland , looks much like any other ageing suburb in the industrial mid-west : a patchwork of small colonial-style houses built after the second world war , with leafy streets and mown lawns .

乍一看，克利夫兰外郊的梅高市，和中西部工业区任何有年头的郊区没有两样：二战后修建的殖民风格房凑在一起；街道两旁绿树成荫，草坪修葺一新。
