Completely agree! I never had a single horse give a problem with stalls simply because I did plenty of education with them. When I worked for one big trainer (who notoriously used to have loads of issues) he used to remember the week before that they had never been in a set of starting stalls
Remember reading an article about Jack Berry the supreme trainer of 2-y-oids who used to canter them in a bunch and then put them through stalls!
Steve Cauthen was terrific, why do ITV waste money employing most of the rest?
