I put a Boston Butt in Humpty last night about 6:30. I was bring the temp up to 230 very slowly so I had the bottom vent open a bit more than I would have had a little on. Than my wonderfull wife said let's go for a walk. When I got back the dome was at 300 and the mestique was bright red across the firebox. No way could a get the lump out to cool things down!!!! [p]The solution was to start up my second medium egg. Pulled Pork for lunch as planned. Go out and get another egg just for back-up.
