Hi! I"m new here and have a question for all you 'pros! I have a 8.5 lb whole pork loin hanging out in my freezer. I want use this bad boy up for our 4th of July BBQ- I need to know- how do I pull this off?! I would like to keep it whole, and I have a weber gas grill with front and back burners. I'm down w/ marninating, or rubbing, but I need cook times and any tips you all might have! I've never taken on anything this big before! Thanks in advance!
