thanks for sharing story, congrats on the bison. i dont imagine it would be alt of fun being "hostage"to one.
-when i was 7 yrs old my dad and uncle were raising pigs, the last one got out one day and wouldnt let us out of our car for 2 1/2 hrs. shortly after he dressed out @ 575lbs. He was a big pig. One day i'll never forget!
