Buy in bulk, what else is there? I think what I consider a normal load out may be bulk for most. The "pile" described above sounds like someone was in my basement. Clearly, it is not hard to amass 40-50 rigs, trust me on that one.What about extra gear directed at SHTF fishing?
Yoyos
Lure making equipment and supplies
Net making equipment and supplies
Buying extra gear in bulk, IE line, hooks, etc
Pack gear, tackle boxes, repair supplies, etc.
Lures are easy to make from scratch, just keep aluminum cans and hooks around. But I also have wire, spinner blades, paitk, skirts, teminal tackle, tons of jigs, etc etc etc
The key, like all gear, is if you never buy crap it lasts. I have only tossed one reel in a lake in 40 years of doing this. Then there are my collectible or antique reels, many of which are rock solid. I bought most of those in the early 80's at garage sales while I was there just to get the collectible lures and knives and such. If I was going to bulk up on gear today I would hit garage sales and Craigslist and buy them by the tackle box and rig. Toss or donate whatever is crap, sell anything with collectors value, keep what you can use. Some day I will die and people will get their grubby paws on my stuff too.
