CC, it's hard to capsulize how TX CNBG do in winter because of the size of TX. Amarillo TX is actually 200 miles closer to Denver CO than it is to Corpus Christi TX, so I would think the CNBG in the Amarillo area would handle the cold better than the ones in South TX. I've seen zero CNBG morts here, but I'm in NE TX. Also, winters here aren't like the ones you northern guys get. It's not unusual to have the heaters running one day, and have A/C running a day or 2 later. If our winters were real winters like you get, I bet they wouldn't do well at all.
