It could stretch to 4 evenings if you were really stingy on how long the fire was on. Plus the smoke put a nasty permanent black on anything near, so we couldn't really use it for heating wash buckets. Obviously, your mileage my vary, and we didn't have the lava rock, so not sure about how that would change it.
