that's what I was thinking, that maybe IMHR is the old registry that merged into AMHA. I couldn't remember for sure what the letters were--and I couldn't see why it would be mentioned now as part of an AMHR show. But, this particular show has an AMHA show the day after the AMHR show, so perhaps it was just a carryover in their show book--someone changed the wording from AMHA to AMHR but forgot to delete that part. That would make sense. The way it was worded, though, there were no non-rated classes--it appears that the intent is to have IMHR horses (assuming there are any!) in the AMHR classes with the AMHR horses and I didn't think that would be acceptable to AMHR. I really wouldn't expect that there are any IMHR horses that will be shown anyway.
Lisa--that's good to know. I'd asked about that sort of thing last year, about offering a few classes for non-registered ponies, just for the sake of letting an exhibitor show his pair of non-papered shetlands. They're nice ponies and would give people a chance to see something a bit different--we don't have anyone else showing ponies in harness here (maybe next year, but it won't be a pair, just singles)--but someone on our committee said no, that wouldn't be acceptable. Not sure if she meant unacceptable to the registry, or just to other exhibitors. That's a good way to add some numbers to a show, though--neat to have the mules and donkeys as well as ponies.
