If you are willing to come a bit North, how about looking in North Central Florida near Ocala? Ocala does call itself the Horse Capital of the World (which makes me giggle).
We are recent transplants from the Midwest and I find it interesting that I don't see as many Arabian's in this area as I would see in SE Wisconsin. But just the other day, I saw a brand new billboard off of I-75 in the Ocala area touting your breed... Maybe that is a 'sign' you should look hereabouts?! ;-D
We know a wonderful realtor who focuses on farms in this area, so if you are interested PM me and I will get you her #.
