Definitely a bad area for being cheap on anything. A few of the places I've looked into only did cubes or seemed pretty sketchy on what they were feeding, so I know what you mean there. And before moving him anywhere, I would definitely check out the feed situation. I'm not going to sacrifice his health to be cheap.
As for what it needs to offer, I am an english rider....low level eventing/mostly jumping and dressage though. But between school and work, I'm probably not going to have much time for anything besides basics so all I really need is a maintained arena.
I've looked around San Juan but haven't had much luck. They were all really expensive or had nothing open for a few months. That one you posted seems kind of perfect though...amazing looking facility and same price as what I'm paying now. They seem pretty knowledgeable too. I'm going to give them a call when I'm finished typing this
