Thank you all very much for your help!
Yeah, now I'm definitely not about to leave Fortune up there. The first day we went up there, we were told he hadn't been used for 6 months but he went beautifully, as if he'd been worked the week before or something.... I know some horses are just like this but I'm not sure if I've had him long enough to know 100% what he's like in that respect.
My boss is being really helpful about this too, she used to be a lawyer herself and suggested that I bring the contracts to show her, and if she can find a way around the "conditions" then we'll go for it. We'll probably end up doing what is suggested above. Lucky for me my dad has a truck and my boss has a trailer she's willing to lend us.
Fortune is really level-headed the majority of the time, not at all spooky or anything like that, so the getting him loaded shouldn't be an issue, but again, I don't know him in that respect.
I am confused about one thing.... If I give 30 days notice, doesn't that mean he has to stay up there for the 30 days? Or does it not matter if we pay that same day?
