True. That gave me the idea of scrap metal being useful for pounding into grommets for a tarp in my current PR, but someone with a crippling vulnerability to Norwegians in steamboats convinced me that more duct tape is a better solution. o3o
Also, I should point out here that the standard improvised shelter uses a # on a green background in ASCII mode, a combination that’s otherwise only used by bushes and shrubs and such.
That has caused annoying amusing discussion when I based the lean-to in More Survival Tools off of the improvised shelter.
