Second, thank you all for your supportive words to me. I'm getting a lid on the crazy, mostly, and a good look at Apollo's legs tells me that yes, my fear of ringbone is ridiculous. He does have nicks and dings and scar tissue from cutting himself - his skin keloids up like it's its job - but he's sound. I do think, though, that I should probably consider hock injections sooner rather than later. I think that would make him more comfortable in work.
As for the jumper's bump,
Looks like I won't be able to run River Glen at the end of July. Not because of crisis of confidence or anything like that, but because I have to be in Manhattan for work the week before. I might could do the Starter on Saturday, but the possibility of having to work through the weekend is significant. So ... later in the year it is.
And ... plans for the new arena at our barn are UNDERWAY! SQUEEEE! Good footing! Dressage training! JUMPING! *dies*
