If you can't financially afford a horse, then you shouldn't adopt one. Don't have too many expectations when adopting a horse. Far too many people call rescues with a whole list of requirements that few horses could possibly live up to.
Most rescues end up being adopted out as trail or pleasure horses.
Of course, some go on to make wonderful show horses on all levels. And many horses are no longer rideable, but are looking for homes are companion horses. Try to play down things like color and even breed or sex. Use the Quicknav navigator to browse my pages and contact the rescues in your area for information on adoption.
