I’ve got a box of a thousand “craft sticks” (popsicle sticks). And, yes, clothes pins are another good choice. 4 years ago, Bob Gross posted “DOT was trying to tell me that I could check something wooden as a container, such as a shipping pallet, but I could not check some wood that was intended for use as fuel.” but I can’t find firewood mentioned – yes/no, carry-on/checked – on TSA’s website. I’ve thought of furniture parts (an old, hardwood kitchen chair, in pieces).
There is some driftwood, but it’s pretty big and wet getting to those island through the North Pacific. There scrap wood from power poles, docks, etc, but a lot of is creosoted or pressure-treated. Wooden pallets used to be used a lot in Western Alaska for firing steam baths, but more pallets are reusable now and especially airfreight has gone to lighter alternatives.
2 ounces of wood = 2 cups boiled is a helpful rule of thumb.
