Most horses find people in their pasture interesting. They want to smell whtever is in your hand because it could be a carrot that happens to look like a camera. If you're in a truck, they have to sniff the truck bed and press their noses against the glass. Of our three horses, Remi is the most curious. I was in the pasture taking pictures and he followed me like a dog. When I stopped to shoot a picture, his nose tickled the back of my neck and sniffed my hair. I turned around and backed up to take this picture. He looked away, like, "What? That wasn't me sniffing your neck."
