OK. I must be stupid tonight or something. Let me recap:
Wild Spot is in Australia and puts the horse to the right.
Iride is in S. Carolina and puts the horse to the left.
Horse poor is in ? And put the horse to the left.
Jazzy in Aussie goes right.
So the horse or the heavier horse always goes to the centre of the road right? OK -- I think I got it now. I'll have to make sure to keep that in mind next summer. Never really thought about it before.
