Here is a link to the club. They are great people. Very helpful and very active in the driving side of things. Lots of shows and events planned throughout the year.
Welcome to the start of your new adventure in the world of mini driving.
Just something to add as I have seen this happen many times before: Please make sure that the harness your buying weather it has a tree in the harness saddle or is a tree-less harness saddle that it has a gap along the spine to releave pressure off of it. Many of the cheap knock off made mini harnesses(and larger ones) are made without this gap and it creates sores on their backs and along their spines when you get to the point where you hitch them to a cart. You can find harnesses for the same price, maybe a little more, that provide this gap.
