I just talked to a lady from your state who asked me if she could drive her six horses up here, if I could take them, for free, she would pay gas.
I'm full; I said no.
Being able to give away a horse is nothing to rely on when embarking on horse ownership.  That is exactly 180 degrees the WRONG way to think of it.  
The market for give-aways, if it hasn't reached the saturation point in your area, soon will.  It has in my area.  I know a lady nearby who has been trying to find 'a good home' for four of hers for 18 months.
And guess what I've found out about many of the people who take these free horses?
You REALLY need to know who people are, because most of them they, sell them for pennies on the pound to a rendering plent, slaughterhouse, or a backyard slaughterhouse.  And you wouldn't believe the conditions in those backyard slaughterhouses.   At least if they have a 30 or 40 hr long ride to a  slaughterhouse, jammed in there with a whole bunch of other horses, at least when they get there, the end is quick.
And if they don't, their life at their 'new home' with someone who knows nothing about horses, isn't very pleasant or long.
Getting an animal without learning about its care, because 'who cares, I can just give it away if it turns out to be too much work or it don't work out'.....
Lord I need to go take a walk around the block, before I say what I really think of that.
Such irresponsibility being encouraged here by people who beat their chests and claim they 'love animals'....
