Hands down - first time I cantered the Clydesdale in my avatar pic.
Riding a Clyde was on my bucket list. Finally finding a lesson barn with one and then getting to the level where I could ride him (he can be a little spunky sometimes so the beginners don't get him as an option) was amazing. The thunderous sound and the feeling of power as he took off was amazing. He's a ball to ride, sometimes when he's really into it he lets out a little playful "happy-buck" a few strides in and then hunkers down and HAULS.
