I am smoking a boston pork shoulder for the 4th and I need some advice because I've never done this type of quantity before. I'm looking at 25 people at 2 PM on the 4th. What time do you recommend I start? I was thinking an over nighter at about 10pm to Midnight. (I have a few guys able to work shifts) How much do you Butt do you recommend per person? Any help you guys can provide would be greatly appreciated. This may be a stupid question but here goes...will three smaller butts (3-4lbs each) cook faster than one larger butt (8-10lbs)?
