Campeau would get on the open road in Edmonton, Alberta, and feel the sanity-saving grace of being alone. It's been like that ever since the Canadian soldier came back from a tour of duty in Afghanistan in 2011 with a crippling case of post-traumatic stress disorder (PTSD).
Crowds made him painfully anxious.
"When I first got back, that was my one escape - to jump on the bike and take a ride when I was getting out of hand," Campeau tells The Dodo. "That was a kind of self-induced therapy."
But the motorcycle couldn't always be there for him. And the crowds - on busy sidewalks and in teeming malls - never seemed too far behind.
"It was like World War 3 every night getting home from work," he explains. "When I went out in public, I started bumping into people. In crowded areas, I started knocking people over."
A psychologist recommended Campeau find another friend: a dog.
