yes the crop trick is great. even better, is a flat bat. the kind with 2 flat leather flaps. makes a racket when it taps, but never hurts them. i keep it flat at my side out of site until the moment the horse doesn't respond to a pull on the halter, or the word whoa. then it comes out of nowhere, gets them and disappears. the don't even see it coming. it's like you have magic powers!!!!
