Watched RH today again-try not to miss it, even when it interrupts my afternoon. Jason Julian's horses are amazing - he hitches them to the wagon right next to a busy road and they don't even flinch when a big semi-truck whizzes by (those truck drivers always seem to be in a big hurry!) . I also like Jason's warnings not to let down one's guard, even with Brabants which are generally more docile and calmer than most other draft horse breeds.
I wouldn't advise anyone to do the same thing, especially hooking up to the wagon with no helper around in a situation like this. He must be really sure of them. I remember when J.J. trained Billings, the stallion on the right side, and now this horse works and stands like he has always been in traffic! Mr. Julian says, he works them year round, but it still speaks to his remarkable training success when horses work like that. Note also how he backed up the wagon on the trailer again!
