The next step in Raf's loading went without a hitch (although of course the trailer was hitched to the car!). He now accepts the front and back bar being fastened and has started to unload via the front ramp. Like many horses, he was deeply suspicious of the ramp itself the first time he was asked to step on it but stuffing a bucket under his nose helped to slow him down and even to just stand still with all four feet on the ramp.
