Well here we are....it's a 11:15am. IT is at 171 nearly 13 hours later. Smoker Temp is at 225. After 4 hours of smoking the IT had reached 137. I thought that was a little slow myself. Anyhow, I emptied the spent pucks and refilled with a mixture of apple juice and water boiling. Closed door and decided I'd bump the temp slider back just a bit because I had consumed a few cold beverages over the course of the night and didn't want this thing spiking on me. So 2am IT is 137*....I get up at 6:30am go outside and the smoker is sitting at 202* and the IT is 145*.....reckon this piece hung around in the "danger zone" too long? I bumped the temp slider over a bit and laid back down. So here it is now 13 hours into the smoke and my IT is now 171*. I'm figuring I'm on the last 2 hours or so of this butt.
