Another point to George's thought. Ark stockers brought in CNBG stock many years ago (at least 30 years)and over time have have adapted to Ark climate (become more cold tolerant). Don't underestimate local conditioning over time. Plus Ark had native BG which are in some cases mixed into the gene pool of CNBG moved (sold ) to the north. It really just depends.
I believe this to be very true! I have CNBG in North Arkansas and I have had freeze overs on my pond of about 1 inch for up to a week. Last year was one of them and I from what I can tell did not lose any CNBG as a matter of fact my BG are doing great this year. So I think some of them are a little stronger then we think....

Or as stated on other posts they have a little North DNA in them maybe to make them a little stronger???
