These Bison were quite a distance away from the viewing areas, but I managed to zoom in enough so that, combined with cropping, I got some 1/2 decent photos.
They have a nice herd of Bison at Fort Whyte Alive and it is nice to be able to see them in the city. They have plenty of pasture to graze. For a fee you can ride on their bus to get right into the herd and take some wonderful pictures. I just depend on my zoom lens for pictures though.
