Road-trip picnics are a casualty of our interstate system
From our US edition
Signs announcing roadside picnic tables once peppered America’s secondary roads and highways. Or so we call those byways now. Before the limited-access interstate system arrived in the 1960s, these roads were primary. America then was laced with a tangle of serviceable two-lane, hard-surfaced highways. Look at an old oil-company roadmap, if you can find one, to get the idea. Some roads were federal, some state, but all were emphatically open-access: get on anywhere, pull over wherever you like. They led through cities and towns, not around them; they traversed the countryside more than they cut through it. They required two-hands-on-the-wheel alertness in drivers, who got to know and respect the lay of the landscape.
