Every time two-lane country roads are widened to federal specifications – from two barely 8-foot travel lanes bracketed by gravel berms to 12-foot travel lanes and 8-foot breakdown lanes – the local temperature increased by a few degrees. And with every new shopping center, with accompanying blacktopped parking lot, the local temperature jumps some more.
