Cori, I too am shocked about the backlash against adoption on here.
Of course no one wants their lives invaded - but why would you object to having a vet or farrier contacted, unless you didn't have one, or they wouldn't have anything good to say about you?
It's my belief that every member of the equine community has some responsibility in the rescue of horses. It's a rescue's job to make sure a horse doesn't go right back into the same situation they were rescued from.
To bash rescue in general because there are some bad rescues out there (and yes, there are. But not ALL of them, in fact I wouldn't say even as much as half of them.) is doing a grave disservice to the horse community as a whole. Where does the responsibility lay, to these animals, in picking up the pieces when they have been abused, neglected, or harmed by their previous owners......well, it doesn't fall on the shoulders of the urban governing bodies, I assure you. It falls on you, and me. Even if there's nothing else you can give a valid rescue beyond verbal support, you all owe them that, at least.
To the OP, the club foot looks severe enough I would not pursue the horse as a gaming prospect, if that is your intentions. He would probably be a perfectly serviceable light-riding mount, but I wouldn't want to stress an already problematic foot to the degree gaming involves. You can find better, particularly at your price point.
