I'm looking to feed a lot of people...roughly 50 people. (Mind you not solely off of one pork shoulder, but there will be tons of other foods, ribs, and various other picnic foods). SO say roughly one pulled pork sandwich per person, roughly how big did I need it to be. I hear they do feed a lot of people, but i'm unsure cause i've never done one before. For those that remember last year when my friends and I had the CCRBQ(The BBQ based on Creedence Clearwater Revival) and this year it's back, only problem is that it's about 3 times bigger than last year. So, any thoughts on how big, or many pork shoulders I need?
