So I don't think that techniqually it counts as barn 4 since we already live there, but since it is now an option I can add it to the mix. I had sent the vet an e-mail telling her about the first place I looked at and my concerns over the glass-legged mare. I told her I didn't want to leave, but that I felt horribly guilty at the deep discount she gives me, and it's not fair to her for me to assume that I can stay. I offered to work for her doing "whatever" to aleviate some of the guilt.
I got an e-mail from her offering to "hire" me to work off the board (I'd still pay what I'm paying) but would work at the barn for X number of hours so that I would work off the rest of the board. If that makes sense. We still need to sit down and go over it, but I'm excited that we might be able to stay longer term. I've already made appointments to go look at barns, and I might still do that in case for some reason I can't work enough for the vet.
