I've found lots of stuff over the years.
Luckily enough my fiance's father Joel works in landscaping and occasionally hauls in massive amounts of stuff from the houses he works on. So i often get first pickin's before stuff gets tossed. I've found (and kept):
-Old military badges. I picked out two that are Navy since I have family members that have served and put them on the strap of my bass. The rest I have stored since I'm scared to wear them.
-Two futons that replaced my bed. One has become something of a guitar island for my many instruments. The other I sleep on. Makes the place nice an cosy for when I have friends over.
-An old bathhouse medicine cabinet. The wood was very old but in tact as luck would have it. So I cleaned up that bitch and mounted it to my wall. It currently stores my incense collection and candles.
-Wii games, specifically Mario Party and Super Mario Brothers.
-An old Casio Keyboard. Its pretty crummy, but I usually run it through pedals if I wan something nasty sounding. I plan on circuit bending it eventually.
-Lots of rich people clothes.
-Some old jazz CD's.
-A scream mask that has since been mounted on the fence to oversea the mess. Might nab it for the lulz one day.
Outside of that, I go to lots of flea markets and thrift shops to scour for hand me downs. At these locations I got:
-Bootleg Pokemon cards
-An original Gameboy DMG model, Fully functional with games.
-A volume pedal.
-A gamecube who's price I heckled down from $50 to $15 (proud of that one).
-and most recently an old battery powered AM/FM radio that functions like an old boom box.
Joel has also dug up guitars before but that was before I came in the picture. So here's hoping he finds on while I'm here!
I'll get pics tomorrow once I'm back at homebase.
