Here's some video of Willow's first clinic, back when she was a gangly four-year-old. She was so skinny, and all legs! That's my Lubbock trainer riding her--Willow had dumped me the day before as I attempted our first canter under saddle, and I was sidelined for a couple days with an injury. Good times!
As you'll see, steering and brakes were still a little iffy, and Willow was most definitely not on the bit yet. Even so, she willingly attempts shoulder in and half pass with decent results.
It's funny to compare this clinic video with this video from February 2008. She has filled out so much, she doesn't even look like the same horse!
