Near Liard, British Columbia, on the Alcan Highway, wild buffalo roam. What's interesting is the only time you'll see them on the road is when a vehicle is approaching. Otherwise, they're grazing. Apparently it's a turf issue. The big males like to let those long-haul trucks know who the real trail boss is. When they see a vehicle approaching the wander out onto the road and stand there. Apparently there are seldom collisions between cars and buffalo. "It's moose, then deer," said the Mountie who stopped me for going 128.
