Any news about Mitch, Emily?
I don't know if you have the time but, if you can't find a local family to take him, you could check the sites of other Golden Rescues in neighboring states.
If you go to http://www.ygrr.org there is a page under "Links" that has the Web sites of other rescues. If they are responsible organizations they would have a transportation system set up.
By the way, take a look at the "Successful Adoptions" photo of Princess in the YGRR home page and you'll see what a good "rescue" does to get a pup ready for adoption.
