I'm an avid horse-lover who is on this game because of nostalgia.
I have basically one goal: to have several breeds with all the coat colors. I've got a few already, but I might try for some more. So if you have a rare color for a breed I already have (and maybe even for ones I don't), feel free to send me an offer (either breeding or selling). Warning, though, if you're selling—I don't usually spend more than 10,000e per horse and I prefer foals.
On another note, I also am trying to thin out some of my stock from the Together Alone and Other Horses tabs, so make an offer! I'm most likely to sell a horse with a common coat, but so long as the offer is fair, I'll consider it.
(Also, I do accept most friend requests.)
