Camp-brewing?

With hopeless hophead hubby traveling at times, brewing has been far more sparse than I, Mrs. Brew Meister, would prefer. I mean, having a stocked kegerator is a nice thing, no? But his recent camping trip made me wonder...

Can you camp and brew? I hear that college kids can do amazing things with homebrewing in dorm conditions. And not everyone (at least not us either) has the super semi-pro dedicated brew stove, racking, kegging system extravaganza that some of Parrothead's work friends have. But, given that brewing is a science, requiring cleanliness, temperature control, and light/air damage prevention...can one brew outside at a camp site?

Where is the most "rustic" and/or least equipped place that you have brewed?
