In addition to gold and silver I like to "stack" (i.e. collect or save for later)....
Knives and other EDC gear. Knives have multiple purposes other than just stabbing things or people. I use a pocket knife quite often. The big black fixed bladed is a little more purpose driven if you catch my drift 😉
I also like to stack memes...
But only the best of the best...
(I've probably shared this one before... It's scarily accurate)
I also dabble in food and water stacking (aka "prepping") but not the apocalypse type... Just the basics like a couple weeks worth of food and water and the means to acquire more should the need arise...
If you made it this far, congrats! This may be my most rambling/nonsensical post I've made!
