Cedar Board Cut Offs - Kindling? (Elmhurst, First and N Highland)

20x16 box of cedar cut offs. It's old and dry so it's probably best as bonfire kindling. At least that's what I would use it for but I have years of kindling stockpiled. Most of it is planed, but there are weathered boards in there and a handful of 2x4 chunks. Almost all of it has nail holes, but no nails. It has not been treated or sealed to my knowledge and certainly not in the 10 years that I owned the fence that this came from.
