Extra fuel/charcoal
Make sure you have enough fuel for your grill. Grilling food is a necessity at tailgating, and the last thing anyone wants is to be cut off of resources. Buy a full bag of briquettes or some extra fuel containers for gas grills, just to make sure you can keep grillin’ and chillin’. It is very common to accidentally leave the fuel valves open and ultimately waste gas. Having extra fuel will prevent your cooking capabilities from being destroyed.
