How do you get your chilled beer to your campsite? In a cooler with wheels - Duh!
You'll need at least two of these for your camp. Maybe 3 or 4. Pack it with dry ice, and that way you'll be able to enjoy veggies, fruits, cheese, and meats while camping. Just because you're going to Burning Man doesn't mean you have to eat nonperishable food all week (contrary to what my friends told me). Dry Ice will last at least 3 days, and then you can supplement with ice from center camp. Trust me, by Day 3 a roast beef sandwich was like a gift from the heavens. And a cold beer? Spoil yourself!
