My signs that SHTF:
A friend in the local government calls and tells me to “hike the trail today” or some such comment.
A friend in the local law enforcement calls and asks to “long term rent” a cabin.
The local farmers and ranchers stop coming to the country store to drink coffee in the mornings.
A friend at the local WalMart tells me there is a special on bread today.
Yes these are all local indicators but I stay clued to the news.
