I watched Marlin Perkins and his sidekick that rode barefoot like the South American Cowboys rope a grizzly. They were successful but they were going for a live capture not a chokedown. So his sidekick got down of the horse to do something. I guess when he was down the horse let some slack get in the line. The grizzly then shakes his head with the slack on the lines and the footrace is on. Luckily Mr perkins sidekick made it to a good tree first.
