Woke up at 5:30am. After double checking everything and getting some coals fired up in the chimney, I got the 8.5# Butt on the rack at 6:30am. I'm using my iGrill2 to track the temperatures, and keeping log entries every 15-30 minutes while I learn to regulate the temps. The 22.5 WSM was running a little hot at 1st, getting up to about 275, close the bottom vents to about 10% each and I have a steady 260 now.
I rubbed it with Memphis Dust the night before. We'll see how this turns later today!
