AM I PREPARED FOR A HORSE?! PLZ HELP!?

Sounds like you have it all Pretty well covered. I would make sure you budget in vet such as shots ext. also have a rainy day fund if you can for emergency's. Anything can happen with a horse. The board sounds reasonable I pay 490 for 3 meals of grain and hay mucking and turn out and blanketing. I think you are all set. just don't jump at the first horse you see look at a couple, but I know there will be one you fall in love with. enjoy! hope this helps
