If the rumors I’ve heard are true, it’s an equestrian, but don’t quote me on that cause that’s pretty prime real estate so it could easily be a developer too.
Either way, tl;dr, OP, HOC isn’t worth considering what with all the changes going on around there. I have a friend who boards her four horses at BarGee (she’s the one who designed their current website, funnily enough), and her mother keeps hers there as well, and I’ve never heard a bad thing from either of them. They’ve got a retired horse there, but money obviously isn’t a concern for them. I know of a few different barns in the area where people have retired horses, but as it seems you’ve discovered, there isn’t really a place around here that is specifically for that purpose, and I’ve been thinking about it for the last day or so and can’t think of anywhere that really offers pasture board or anything like that.
Travesty Farm out in Apollo was always a good place when I was there and there were some retired horses, but that was 10 years ago. They do have ample turnout and as far as I can tell, their schedule hasn’t changed since I was there (8-4 during the winter, 4-8 overnight during the summer), and it’s also less than $400 a month in board (care was always good when I was there and they had a farrier on site, land is just cheaper out there than it is up north so they don’t have as many taxes to cover). They’re an eventing barn, but they might be worth looking into for your retiree if you want to bring him up here.
