I think I get the picture now!
I like your idea about the colts.
I picked up a badger hole on my ol yeller horse at a dead run one time. Way worse than gettin' bucked off!
I learned a neat trick a week or so back at a branding. Old feller had some smooth hot wire up for bulls and it got knocked down and was laying in the grass. I thought I was past it, ridin' my colt, when he picked some up on his hind feet. Couldn't step over it so backed him up and stepped off and got him untangled. Looked like a good way to get him used to not fighting wire around his legs. I wondered if a feller left some around for colts to walk thru' so they would get used to stuff like that. 'Course I suppose they could get hurt. Maybe not to good of an idea after all!
