I was able to borrow a saddle yesterday and cantered Bourbon for the first time since I adopted him. I even popped him over a little crossrail a few times. He loved it! I couldn't get him to pick up his right lead, but we'll work on it.
I rode him again today and he bucked a bunch. I'm pretty sure it was because the saddle doesn't fit, so I won't be riding him in it again. *Sigh* Not being able to ride sucks.
