Yep. So close to the road leaving Banff that Park Rangers were using bullhorns to get gawkers (including us) back into our cars. No fences or culverts for protection, but happily a mom who seemed crankier about the behavior of her rambunctious cubs than their audience. Had she changed her mind, she could have reached us in seconds, regardless of my telephoto lens.
I took this photo of a bear prop near the road leading into Red Rock Canyon at Waterton Lakes National Park, convinced it was likely to be our only wildlife sighting on the trip. And then we turned the bend… (I do have a reasonably good telephoto lens on my camera, but without a tripod, not the steadiest hand).
