Great pics G, that one of the wild horses (?) is real nice & of cours the views around the river are just awesome.
Those are bronze mustangs. I don't remember the story off hand (been years since I was there before) and someone destroyed the little monument plaque so I couldn't read about it...
Well all I can say is if I ever get the chance I'd love to come over & view all the scenic areas. Probably wear my camera out but it sure would be worth it.
