Charley Boorman is back on his bike exploring the world's second largest country - home to some of the most stunning and challenging terrain known to man.Canada is a country of extremes, and Charley knows all about pushing the limits.He goes dirt biking in New Brunswick, dives through old shipwrecks in Tobermory and rides along Butch Cassidy's old Outlaw Trail.He also meets a fascinating mix of people on his journey.As he heads across Canada, he plays ice hockey with a legend of the game; spends a day as a Mountie cadet and nearly meets a ghost in Winnipeg . . . Written with Charley's trademark enthusiasm and humour, Extreme Frontiers is fast-paced, hugely entertaining and packed with adventure (and rather a lot of mosquitoes).
