I'm not sure if I'm a hoarder. I'm sure I'm not a collector because I don't follow ay one theme in depth. I've concluded I'm a gun accumulator!
I have more guns than I can keep track of, every trip into one of the safes is a new adventure. Probably half of them I've never fired. That part used to bother me but I see them as my retirement fund, so I've stopped being concerned by that.
After considering the origins of this depravity I've come to realize what I like most about guns is buying them! The first time I walked into a store and bought a gun, back in those turbulent years of the late '60s/early '70s, I was awestruck to exercise that freedom. The government(s) that wouldn't trust me with a firecracker, that had no regard for my existence as evidenced by the draft and the pointless waste of life it was feeding, would allow me to purchase any sort of firearm and just take it and shoot it anywhere and anytime I chose.
That feeling of freedom and joy still accompanies each new acquisition!
My "plan", if I have a fruitful retirement, is to deal with every orphan gun in my safe one at a time. Get one out, address any deficiencies in function or appearance. Take it to the range, develop loads for it, get it sighted in, get to know it, enjoy it... and hope it catches the fancy of some other shooter with deep pockets. That should keep me happy, occupied and funded for a long retirement.
