Robin, whether or not you should enter your Cremes in the show is a question only you can answer.
If you're bucking for sweepstakes points or legs, obviously those are negatives to what you're asking us, based upon the fact that you're the only exhibitor.
If you're looking to encourage potential breeders to consider raising cremes, that would be an upside.
As good as my white satins tend to be at times, I get far more compliments out of red satins than anything else, not because they're better than the others I bring, but because they're different than what people are accustomed to looking at.
Here's an option: Show your best rabbits, but bring along a few of your lesser rabbits for display during the event and take your best back home when the judging is over. At the end of the day, the fairs usually just want an animal on exhibit and don't care if the rabbit you won with is there all week or not. Now way in the world would I leave one of my best rabbits on display for a week at a fair for people to shove corndog sticks, cotton candy, chocolate bars, etc., into their cages with each passing day.
