Can anyone say what kind of material is used to chink or seal between the horizontal logs on some of the shelters in the south? I am thinking of the Sam Moore Shelter as an example. I know there must be others and I don't know if the material is the same either. We don't have the gaps between the logs sealed here in Maine. It looks like a little more protection from the elements or is there another reason for sealing these joints? Just curious.
Thanks,
