You know what is really sad? 3 years ago (when hay was affordable and I had my own farm):
$900 each
(not including mortgage payments on the farm or maintenance though, lol)

Now:
$3500 each
based on self care board
...now if I added how much gas I use to go the barn every day... an extra $650 per year

Both figures include hay (on grass in the summer), grain, farrier (barefoot), shots, deworming, annual vet/coggins
Not including tack/equipment, recreation expenses, emergency vet calls.
