Durn dude, I'm really impressed!
39 butts, average 8 lbs
= 312 lbs x 60% yeild (the looked pretty lean)
187 lbs product divided by 1/3 lb/serving-sammich
= +550 servings
That's really impressive numbers for a trailered pit! If I'm ever close enough for one of your pro bono cooks I'm in (just for the learning experience).
Got a bunch of cooking toys and a custom metal fabrication shop where I spend my time building all sorts of smokers & outdoor cooking gear.
