I see them in the results at Ft. Collins from all the way in NV,UT, and SD, never understood how they made that work though.  If they are a pure bred try the appropriate association newsletter/website/magazine or hit up a national show and see if someone needs to expand.  Newell is the only other big sheep one I can think of that would be anywhere remotely close.

I am sure the guys at Ft. Collins would advertise a dispersal before you sold them.
