From personal experience I can tell you these animals will charge thru gates, fences and the walls of buildings, although they could be hand fed, if you kept your eye on them!

I asked the ranger at Farewell Bend park in Idaho (where Lewis and Clark said farewell) just what was the problem with that fence there. The "fence" was made from 12"X12" timbers... a six foot chunk of fence was missing... he said a bull bison got an attitude. The person who was teasing the bison lived.

I saw a old-style Caddy DeVille that lost an encounter with a bison. Both were parked when the challenge was taken. The Caddy lost. big time.
