Since theyre growing up and don't really have a care in the world.
I'd absolutely HATE to be Spirit, I wouldn't want to go through the hardships he went through - maybe at the end, but certainly not at the beginning. I wouldn't want to be Esperanza either since she went for so long missing her son and wondering if he was even alive.
Rain, maybe, she'd be my next choice.
Colonel? Hell no, I wouldn't be able to abuse animals like that if my life depended on it.

wild and free

Rain. She's so pretty!

Best character.

Rain to run by spirits side throughout the day

I love her!

Spirit because he is so awesome

I'd want to be spirit because he is: smart, strong, fast, can NEVER be broken, and who else can jump a canyon with a person on your back.

I want to be able to throw people off my back with a badass song in the background like spirit.

Rain or Esperanza. They both went through a lot. Plus I love adventure like Spirit and I am very curious. I like Esperanza because she had a foal. Not to mention she is gorgeous. I consider myself ugly though because I am a twoleg and twolegs are ugly. there are so many more reasons but I have to get off soon so.

Spirit. Hes free and loving and is willing to sacrifice everything just to be with those he loves
