My husband and I took 2 extended trips this year, and fire pits were a real issue.  We cook most of our suppers over a small fire with a small packable grill, and most of the firepits had become un-usable (over built, full of garbage and unburned wet logs.  When we entered for our second trip, we were given a Littlebug wood stove to try out and critique. It was awesome; takes very little wood, boiled water in less than three minutes, and we could add wood to create enough coals for doing a creditable job of frying fish, baking bannock, etc.  It burns wood down to a scant handful of fine ash; easy to dispose of.  On one island on Beaverhouse Lake, the firepit was completely unusable; we set our Littlebug on a flat rock, enjoyed a fine supper, and enough of a "campfire" to enjoy the rising full moon.  When we departed, it took minutes to clean up and leave no trace.
