I hope I don't get in trouble for cross posting but things are a bit desperate.
If you are looking for a new mount or know someone who is please check out my dressage mare in the giveway forums.
I'm very sorry for your troubles.
Have you spoken with your trainer, local trainers, not so local trainers,local vets, farriers etc, posted them on dressage classified, your local feed/tack shops, community boards etc, etc - there may at least be someone that is able to pasture board them while you sort out homes.
I have done as much of that as possible and am continuing to do more while dealing with the rest of he madness going on right now. Every time someone suggests some place to post or someone to contact I am doing it.
It's breaking my heart. I delivered both of them. In addition to loving them like family members, it is unlikely that I will ever be able to afford such a nice dressage mount again. She really is outstanding, only limited by me.
Have you put flyers up at Robert's Market in Woodside? I have bought and sold horses off of that bulletin board - lots of horse flyers, and well, the vast majority of Woodside (very horsey!) sees that board.
Also, contact Woodside, Portola Valley, Moon Valley (half moon bay) pony clubs.
Sorry you are in this position. Its heart wrenching When things went down the tubes in 2008 - I found myself looking for a new home for my heart mare. I was able to keep her at a friends ranch on the coast ($250 a month pasture board - PM if are interested) to get me through the hard times.
