Hi!
Wow! What a great group of people and so diverse!!!
I partly answered this in the "what are your hobbies thread, but I'll expand a bit"

Post cards: I've gotten them from almost all 50 states and one from australia, 2 from new zeland, 3 from england

Rocks: When I go somewhere and am outside exploring or if the place means something to me I pick up an interesting rock to remind me. Inspired by a story I read called "A Rock for Remembrance"

Knives: Like I said before, I collect them. Some of them are new and shiny. Most are old. I go to antique stores, flea markets, or people who know about my hobby just give them to me and I clean them up, sharpen them and occasionally carry them. My favorites are the old whittling knives. I've still got the one my granddaddy gave me when i was 8.

Books: Lots and lots of books. Especially old ones. I'd be happy if my only furniture was a chair and bookshelves but my partner would probably shoot me.

Zippo Lighters: I love 'em! I've got 5.

Oh! And baseball hats. I have 34.
