Somebody just posted me .... will look for it at the next gun show ... there’s always several tables of first aid and emergency preparedness stuff ... complete backpacks for sale too ...
Yes, that’s one of the ways I made up the contents of a lot of stuff in my bags.. gun shows.
There is always a decent survival preparedness type table and someone is always selling survival food so I take advantage of gun shows to stock up/upgrade, or rotate my bags contents.
