I'm not sure which category this falls into but another thing horses are scared of is things that you make weird noises, only you can't see them...the goats! The kids are in one of the spare horse stalls with the bottom half of an outside door open so that they can go out into a fenced-in run. When the horses are in the barn, they can hear the kids without being able to see them. Let me tell you, these kids are vocal ;D This makes for some spooky times in horse minds. Ears prick up, they leap to attention; there was even some snorting! It didn't help matters that the wind was blowing a gale this weekend which adds to the category of things that are moving. At the end of the day everyone survived the spookiness...I did have to walk Solana up to the stall door and let her stick her nose in and check out these funny new neighbors. What a hoot!
