July 4th! About 3 hrs total! Started with temps right at 250. About 40 mins into the smoke the temp dropped to 200. Added more RO and the temp stayed at roughly 265 for the remainder of the smoke. I could not get the temp down. Final breast temp with a digital thermometer was 184. The breast was a bit dry.....but I was very happy with my first smoke! I used KIK-N-CHICKEN Weber rub!
