TRAILBLAZERS: A ROCKY MOUNTAIN ROAD TRIP

BBC Two, 9pm

Ruby Wax, Melanie Brown and Emily Atack – the, er, trailblazers of the title – continue their journey across America inspired by intrepid 19th-century Yorkshirewoman Isabella Bird, who visited the Wild West at the height of its notoriety. This week they reach Central City in Colorado – during the Gold Rush it was called the richest square mile on Earth; today it’s a gambling hub, naturally.
