I do Single Pleasure, mainly because down here we hardly ever see Country Pleasure, even though our driving horses fall way short of the standard of US horses with respect to Single Pleasure Driving.
My current horse is more suited to Country, and I am hoping that our show schedules this year will include Country classes. The trouble is that there are very few harness horses here, especially Cat A. And there are more in the South Island than in the North Island.
I haven't tried Roadster yet, but may do this year. And I really like Obstacle Driving too, but we don't have a lot of those classes either...
I've only been driving minis since last December, but I love it!
And would encourage everyone to at least give it a try.
