Ambient temp about 28. Supposed to be down to 10 overnight. Should be a good test of the number 2 with this 11 pounder. I'm estimating about 14 hours....Hope I'm close.
Thermometer is thermopro tp06. http://www.amazon.com/ThermoPro-TP-06-Digital-Roasting-Thermometer/dp/B014DAVX8K Seems to be an ok therm for $25.00. Only negative is the absence of an on/off switch. Battery removal is quite simple.
