FTF, someone who is very active with the Foundation horses has been reading this board for some time now. They happened to talk to ALL 3 of the foundation registries and during the course of conversation just happened to ask if anyone there in the office knew "Susan Larkin" like you claimed they were clients of your's. Funny thing, NOBODY knew you or had ever heard of you.
I asked a couple people I personally know which were names you dropped to validate yourself. Again, they either didnt know you or ever heard of you, OR, they rolled their eyes and said you were an idiot who couldnt ride.
People have been breeding horses for hundreds of years without your help. There is no need to re-invent the wheel and to think a horse you cant even get out of the barn is going to have a lasting effect on the integrity of the breed is a lofty idea at best.
Also, if mustangs were all that and a bag of chips, dont you think ranchers would have stuck with them instead of breeding horses that could do the job better? You can get those suckers for free!
