Thank you all for your advice from your years of experience. We did agree to do the wedding,and I never would have moved forward without all of your input. Consequently, the wedding went off without a hitch. We few 250, and got rave reviews.
I smoked the butts over several weekends, vaccuum packed, and froze them. I thawed them in the fridge for a few days before, and then brought them back to life in a few turkey fryers on Saturday morning. I pulled them and put them in large roasting ovens for serving, and then added a finishing sauce right before service.
We also did Dutch's Wicked Baked Beans, pasta salad, green salad, and coleslaw. I had squeeze bottles of finishing sauce and bbq sauce on the table so people could adjust their sandwiches to their taste.
The highlight for me was when a man came in the kitchen and stood beside me. Once he caught my eye, he said, "Son, I have spent 64 of my 67 years in North Carolina, and I KNOW BBQ. That was one of the best sandwiches I have ever sunk my teeth into. Fine job, son." I couldn't say anything, I just gave him a hug!
Thanks again, everyone for sharing your experience, knowledge, and opinions. There is nothing better than community!
