A grade CAN be a cross breed (not saying gypsygirl said they CAN'T, but just made it seem like they can't, just wanted to specify!)
A grade horse, to me, is a horse who is either registered or unregistered but their registered name, parents or breed is unknown.
We have a registered Morgan mare, but we don't know her parents or registered name or have her papers, so she'd be considered grade. We have a STB/QH mare, she cannot be registered and we know one of her parents, so she is grade.
Alot of people have different opinions on what a grade horse is, to some it might be a horse that can't be registered, to some it might be a cross breed, etc.
Grade = unknown, basically.
passion is when you put more energy into something than is required to do it. it is more than just enthusiasm or excitement, passion is ambition that is materialized into action to put as much heart, mind, body and soul into something as is possible. // <3 starlite - dream - lady - georgia
