Well it's over and I'm happy with how it went, I don't know how many people showed up, don't think it was 150 as was planned for. The smoker ran great and I was able to hold temp over night well. My wife helped pull and also made the slaw. I got quite a few compliments on the pork, even a couple of best bbq they had, but that was from friends and neighbors.
I just used Bad Byrons rub on all of it to keep it consistent and wrapped at around 160 to 165. It was a lot of work and I had fun. I guess it was probably luck that it turned out the way it did or the Lang smoker is really that good, or both.
That leads to another problem, I had my mind set on a Shirley smoker when the time came, and now I think its coming sooner, but now I'm thinking that the lang is a possibility even though there are things I don't like about it, it sure turned out some good food.
Thank you to everyones advice and encouragement, y'all helped make it happen.
