RE: Is my buddy a hopeless gun nut?
Nope, your buddy sounds normal to me.
We have three gun safes here in CA (wouldn't be here except for USN)and two more in Nevada. It is like a disease for which I will not seek a cure.
Even the wife gets involved....two years ago I went shopping for a pre-64 M70, NIB and came back from the first day of the show -almost- in tears, like some sort of withdrawal. Wife suggests we go to the Harley dealer....drove out with a new wide glide. For my birthday that year she got me a BFR in .500.
