(Yes, atomic buffalo turds)

Has anyone made these before WITHOUT using a smoker? I don't have one but I want to take them to a tailgate. What sort of adjustments should I make? Should I cook them ahead of time? Or just do all the prep beforehand and throw them on the grill at the tailgate?

Here's the recipe I'm planning to reference in making them: http://www.mrbaconpants.com/atomic-buffalo-turds-with-pulled-pork/
