Boarding near me is typically like this:
$100 a month for partial care. Which includes stall, water, one feeding a day, and unlimited access coming and going, indoor arena and pastures.
$250-300 for full care. All feedings, stall clean out, holding for vet/farrier, turn out, arena , pastures, turn out and so on.
Really wonderful facilities all over near me, within those price ranges.
