I've got the food dehydrator running with smallish amounts of foods to reconstitute/recook and eat to see how they turn out. A sliced-up orange (will eat that w/o rehydrating), some cooked lentils (to see if they cook faster after being precooked and dried), brown rice precooked in the same way for instant rice on the cheap, and a recipe for pesto I found in Trail Food, a really nice simple book I found at the library.
I'm getting a yen to pack up my pack and a week's worth of food, ask our campground owner/manager/my boss for a tent site, and live in my tent out of my backpack on dried food cooked on my camp stove for a week. Because (confession time here) I've never done it for more than overnight.
Well... maybe 5 days. That's about what I figure between town trips on the Appalachian Trail.
