I really don't recommend falling off draft horses...my first fall (and my 'only fall' so far) left me with a concussion and threw my neck out of wack. Not a happy time...but it could have been worse!! It's a six foot drop to the bottom and could you imagine getting stepped on by a 7.5" wide hoof? I haven't fallen off since, and I try hard not to!!!
But they do say, there's a first time for everything!
