For Father's Day, my wife/kids got me the ebags crew cooler, and it's one of the best presents I've ever gotten.

I take around a dozen frozen breakfast burritos, powerade, about a pound and a half of corn nuts, some little debbies, microwave popcorn, wheat thins, and string cheese. Gets me through a 4-day and I usually don't have any food left over.

Someone on here (Kansas?) gave me a recipe for jambalaya, and I was carrying that around in frozen containers, and it would stay frozen pretty well. I'm a huge fan of taking food with you.
