SR are you going all PETA on us taking their freedom away??
I like #4 as well.. and the should tattoos are great. I got one a few months ago.. It's a heart but a horse head and the word love written in it..
But a horse will only really let you borrow its freedom and ride without hindrance if it doesn't mind you up there.
My horse will buck the #### out of you if she doesn't trust you. But me, she will sidle up to me and let me hop on, as long as some point during the ride I give her free time to run around and steer herself. That makes it FUN for her!
