East of Fort Macleod, 105km (65 miles) north of the U.S. border and 216km (134 miles) southeast of Calgary, Lethbridge is a delightful garden city set in the deep, beautiful Old Man River Valley, and a popular convention site (it gets more annual hours of sunshine than most places in Canada). Lethbridge started out as Fort Whoop-up, a notorious trading post that traded whiskey to the Plains Indians in return for buffalo hides and horses. The post boomed during the 1870s, until the Mounties arrived to bring order. Today, Lethbridge is a pleasant prairie city and Alberta's third largest, with a population of 66,000. For details, contact the Lethbridge Visitor Centre (2805 Scenic Dr.; tel. 800/661-1222 or 403/320-1222), open daily 9am to 5pm.
