We see our animals running free all over Wyoming and it's not all that surprising to see a horse or goat or sheep while you're driving down the road. Apparently it's a little less common in other places like Pennsylvania.
Few things in this life are as pure as this video. Living in Wyoming where we have more horses than most places we probably get to see more videos of horses acting funny and playing around. But this is pure happiness coming from a horse playing with a butterfly.
