As everyone stated, $600 a month is rediculous. At the barn I ride and work at full board is only $525 and that includes a nice sized stall (I can't remember what size off my head), they are on a strict schedule ( I know, lol, I work there), nice fluffy shavings in the stall, stalls/hay/water done, blanketed when needed..etc..etc..very nice though. A nice club room and tack lockers included, a super nice BO, and nice big lighted arena and tons of awesome trails. No way I would pay $600 for what you described, no offense.
