Playing along with Jane at
Small But Charming in posting old pics of ourselves. This is me in August 1967, at 15 years old, taking a horse named Cocoa over about a three foot jump. Aside from my turned out toes (a life long riding problem), my form is not too bad. My arms are slightly bent, I've got light contact with her mouth. I'm not behind her momentum. Looks like I grabbed a handful of mane as you can see from my first two fingers, but I'm letting go now that we've taken off.

Cocoa was just a camp horse, ridden by a different kid every day every day of her life but she could jump pretty well and I jumped her a lot that summer. This is the only time anyone snapped a pic.
Can you see my tongue sticking out?
Lucky I never bit it clean off.
