You've got the idea. And though I did at one time (40 years ago) I don't collect, I just happen to own a few.
Yeah, so did I until that morning a couple of years back when my cat had levelled a 12 gauge at me while I slept and I woke up with two barrels in my face. He said, "Canned food. Now! Move it!" Coincidentally, that's about the time I quit drinking.
