While I am not into prepping, I recently had a conversation with a Prepper that triggered some memories. He commented that in a shtf situation there would be people more ready to steal from him rather than go out and get a rabbit.
In MN I spoke with an older gentleman who had lived through the Great Depression. He told me of a time when he had tracked a deer through the snow for two days. Then a set of footprints from another hunter intersected his path. He realized the other hunter would reach the deer first, so he turned around and headed for home cold, tired, and hungry.
I remember the time in Illinois in the 1950s when getting a deer hunting permit was a huge thing. Actually getting a deer was an even bigger challenge. Like MN during the depression, I suspect the deer were hunted to the point where finding one was a rarity. Of course, it can take many years for the population to rebuild.
My point is that if one plans to rely on hunting to provide food in a time of broad spread crisis, they may want to consider a plan B. There will be many others with similar intentions. Getting a deer or a rabbit may not be as easy as it is now.
