We used to put on a pig roast in our neighborhood every year on Labor Day. We lucked out every year for the 5 or so years we did it. Perfect weather every year. That first year we were sweating bullets, because none of us had ever roasted a hog before and weren't for sure how it was going to turn out. We had 200 people showing up and weren't for sure if we'd have bloody pig or burnt charcoal. It took 8 hours in the roaster and turned out absolutely perfect. It's hard to beat the flavor of a well roasted pig.
Several years later a buddy of mine was roasting 2 hogs for his wedding reception. We got up early the morning of his wedding to cut up the hogs that had been roasting all night. We had lots of offers to help, but nobody actually showed up. That was an intense morning as the 2 of us tried to cut up 2 whole hogs before it was time for the wedding.
Those pictures you posted brought back the memories from all those hog roasts. Always fun for me and looks like you guys had a great time too!
