I'm a hard core hunter, fishermen & gatherer. We live rural and can do most of this stuff right out the back door, but it's also a serous hobby of mine, so I travel to many places to enjoy these activities.
Have already put (4) deer in the freezer, shoot a few squirrels and rabbits, some years a turkey, some years a couple wild hogs or an elk, always have lots of fish, gather mushrooms, rasberries, blackberries, etc.
Processing, preserving and eating what you harvest is a big part of the fun for me, and it's some of the best, most healthy food you are going to get. We eat what we take, or we don't take it.
Add a big garden on top of this and we eat pretty good. We also provide supplemental heat for the home and shop with firewood I can easily procure on the back forty.
Now the bad news ...... I would be lying if I told you that we did this to save money on the grocery budget. I'm sure we could be eating prime rib and crab legs cheaper when you factor in all of the expenses including; owning the farms, travel, licenses, food plots, tree stands, boats, tackle, firearms, ammunition, clothing, motels, trespass fees, gasoline, wear on vehicles, etc.
