Elk cows like to graze on the lawns of Estes Park, Colorado. Bulls follow them into town for some lovin'. The scenes in this video from Human Planet are surreal, particularly the golf courses crowded with both humans and elk. Also, very stupid tourists.

I live in Alberta too, and like Agricola says this happens often.
I have a photo of a line of tourists hiding behind a lamp-post from a gigantic Bull. The Bull moves and they move all in a line, just like a windsock or something.
A cow ran into my car at a downtown intersection and did about $2,500 in damages. The elk jumped up and ran off.
