We had those "mid size bales", that had 4 long strings, weighed over a half ton. I am sure I didn't do it right, but I just ran it through the mouth and crossed the ends under the chin like a curb strap, then back through the mouth, which I think is the wrong way. But you have to keep in mind these were horses I could of just looped it around their neck and neck reined anywhere. I am no means offering advice on how to use one, I just thought it was fun as a didnt know better kid :)
I DON'T LEAD 'EM AND FEED 'EM, I RIDE 'EM AND SLIDE 'EM.
