I just got home and I can't stop smiling. I rode an adorable Arabian/Saddlebred cross (I know it sounds weird but he was great). He looked more like a Quarter Horse with a pretty head than anything else though. He was pretty disinterested in me and tried to refuse to go into any corners in the arena, but it was still great just to be on a horse again. I remembered so much more about riding/tacking up than I thought I would.
I gained a lot of weight after I stopped riding, so when I was walking into the barn I half expected the instructor to look at me and say, "you expect to learn to jump on MY horses? No way fatty!" But luckily nothing mortifying happened. We pretty much just trotted the entire lesson. I've lost the balance I used to have, so two-point was a disaster. I can still post well, I just can't do ten other things while I'm posting the way I used to. No cantering today which was probably for the best considering my newly discovered balance issues.
Still, I'm happy. And I'm going back this Tuesday.
