I don't have any serious collections, being a broke college student tends to prevent any serious collections from starting. I do have some small ones though.
-Random WWII and Cold War military stuff. I've got a Gebirgsjaeger WWII backpack, WWII badges, bayonets, camo coats, a DDR NVA helmet and some other stuff.
-1/35th scale military models. Back when I worked more there were probably over 20 kits in my stash. I've got a ton of built kits and I've actually won a few awards for my builds.
- For every European city I visit I try to buy a patch of the city crest or something similar so I can put it on my big back pack. I look at them like kill marks on a fighter plane.
-Like everyone else I've got a lot of beer glasses. I tend to focus on ones with beer company logos, and hand painted "steins".
