Thread drift a bit.
Leaving Jasper NP on the way to Lake Louise a few days ago, we were told by the tour director that there were so many deer, elk, bear, car collisions, that they put up short fences along the roadway and built overpasses every couple of miles to funnel wildlife over the highway.
Well, nature being what it is, the wolves caught on quickly. They then waited in the shadows close to the bridges and pounced on the wildlife crossing.
