in the 2011 breeding season I got 3 females from the other breeder in our reptile company. he's about 45 minutes away. all 3 had good clutches that year from my male. going to breed 2 different females this year again from him. this is no where near the distance that you will be going. but it was a change for the females that could of cause problems. he has the open snake racks like the freedom breeders. I have the reptile basic cb 70 racks which are much darker and maybe they felt more secure in them with less stress. like others that posted, I can see a move causing breeding issues. but, if you do decide to do it. in the move, keep them warm. I take my coat off in the car and keep the temps in the car more for the snakes and hotter than I would like it.
keep the stress down as much as possible and good luck.
