Man, I hope the mare recovers well. That is a scary place to get a wound that won’t heal. Why does it seem that the nice ones end up facing these situations, and the crazy horses skate through life without ever having a scratch put on them?
I would also be uncomfortable with the thought of someone unattended on my property. I think sometimes people stretch the truth when they are trying to get some official response to a complaint. It is entirely possible that the woman never got closer than the road, but told AC that they had been on your property in order to make their complaint more viable.
Also, I think a lot of people have a hard time understanding that even though you have a sign out, advertising boarding, that doesn’t mean you are “open” to the general public. I was finishing up in the arena the other morning and a strange man pulled in from the road and stood around by the arena gate. I asked him if I could help him and he explained that he lived down the road and wanted to know if he could “rent” the arena for his daughters to ride in when he didn’t have the time to haul them to the arena their riding group practices in. Now, mind you, there is no sign up where I board. But he had seen the barn through the trees, trucks and trailers (lots of people haul in here for lessons) and the arena, and figured it was a “public” facility that he could just pull into.
Anyway, good to know that the AC was accommodating after seeing your vet records. I hope you get good news on your mare.
