In spite of the camera and video equipment that takes up the majority of my pack space I always find room to pack a widget can of Guiness (and homemade smoked tuna jerky) on my trips to photograph the lava flows. Since SN Torpedo in a can has appeared I hump a can of that into the shoots too. Kind of a inpromptu black & tan, as it were.
Whiskey-wise, it is too dangerous out on the lava to be drinking spirits. Besides, Pele prefers gin. However, tradition has it that there is a tailgate feast upon returning to the truck, to celebrate a safe return from another visit with Pele. At the tailgate feast anything goes. It's all packed into a cooler awaiting my/our return.
