I also have small children with me and would like to have the fire burning at all times to keep the bugs away. ' 'I really dont see giving up that much of the wood as I cannot risk running out myself. We are camping way too far out to get access to additonal lighting. I tell you what if you will let me have 2 of the fire wood I would be willing to give you two of the food items. I know that racoon probably took your food as well!!' 'Okay that is a deal.
