No shelters will last as long as those caves where ancient troglodytes dwelled, not even the shelter on Blood Mountain. We have books, photographs, libraries and art galleries for that purpose.
Bulldawg, see post fragment immediately above for an example of a trolling post.
Mags, note how I quoted bfitz.
bfitz, hope you enjoyed your visit to Eagle's Nest Shelter. Thanks for using its register to record your visit.
We all know the purpose of shelters is to concentrate impacts upon an area chosen for its ability to absorb those impacts and thus discourage spreading the "blight" throughout heavily visited areas by those who don't know or refuse to employ LNT techniques.
