Hi. I just signed up. Found the forum because I am currently in stall with a 4 lb. chuck roast in my smoker and I freaked out. Ran straight to the computer, Googled smoking chuck roast and found this forum. Thanks for calming me down. I have been at 162 for 3 hours then it dropped to 159 for the last hour and I lost all self control. I'm new to smoking meat....only smoked a pork butt, top round roast and ribs so far. Still learning...I have a lot to learn. Thanks again!!!
