Omg I saw those horses on craigslist and was like "wtf is this person thinking?!?". I'm so sorry that you're having to deal with this. I can't imagine she's going to get the money she's asking for either of the two horses I saw her post.
This being the other one:
Half-Arabian Gelding
Also - is there someone at the house/property all the time so that she can't come by whenever she feels like it and access the horses? This makes me so angry and knowing that you're also here in reno makes me want to find her and slap her. Haha - entitled people upset me (obviously). If there's something I can do to help, idk how or what, but you let me know!
