btw, that was probably not what I was eating this weekend. Dad did a LOT of meat and I think he only spent like 3-4 hours on it that morning, total. I only got there in time to eat and didn't see what temp he was grilling at, but there's no way he was slow cooking.
Was still impressed with how it all came out, though. His is a Pit Boss. Might be a better smoker than my Traeger. I'd still say, for whatever amount of time he kept the patties on, I could still taste it and it was much better than not having smoked it.
