Dusty is 3 now, and had all winter off since October. Before anyone jumps my case, he was started last year towards the end of summer/beginning of fall. All rides were under 15 minutes, nothing hard. Got a ride once a week. I had him doing the basics just enough to show at the end of the year show for the Stakes class.
Here is a video I got of Dusty today. He retained a lot of stuff he learned, but was a bit rusty in some spots (lol at the failed right lead). I too, was a bit rusty, it's been hard for me to get out and ride the past few weeks.
