We had our own horse and used to board a few more. Sometimes the neighbors' (they were paint breeders and always had more horses than they had stalls), sometimes others'.

It took us a few years to learn this: you have to be stone-cold all business to board horses without having any issues. People who don't keep their horses on their own property simply aren't committed enough to put in the time/effort/money to take care of them. So you either end up feeding them, cleaning stalls for them, watering them, etc. etc. etc....and you never get paid enough for your trouble.

No more other people's horses on our land. Ever.

I feel for you--we've been there. BTW, I'd keep an eye on your daughter's friend when she's riding. If there was an accident I have no doubt her mother would be thinking about a way to extract some money from you.
