You might ask some breeders about older hold-backs they may want to sell...they might have them but not drag them to all the shows as they take more room &
most buyers want hatchlings. I like Okeetee Corns too & used to breed them. I still have one but he's 20 years old, a little old to call a "hold-back". And if you
like the look of Okeetee, you might also look for Abbotts corn snakes. (they tend to have heavier black borders between the reds & oranges, really pretty IMO)
