Paul Wade: "Americans are often accused of bragging that things are â€œbigger and better in the USâ€. While that boast is arguable in many cases, when it comes to autumn colour, the New World wins hands down.
"In much of the northern hemisphere, leaves turn soft yellow and brown, with a splash of red here and there. But these are mere Roman candles compared to the pyrotechnics in North America. Photographs canâ€™t do justice to the startling scarlet, gold, purple and orange that blaze across hills and sweep into valleys. Views are beautiful for the first-timer â€“ but just as memorable the 50th time around. Best of all, this annual show is absolutely free."
