Yes, maps. As a person holding a degree in Geography, I'm apparently expected to know where everything on the planet is. Unfortunately, I do not. In fact, I suck the worst at Jeopardy when the category is Geography. I only took 2 regional geography classes in college and they were North Carolina Geography and Latin American Geography. I can tell you most of the capital cities in South America, but I can't tell you where the hell Korea is.
This is why I collect maps. And atlases. They are always fun to look at, especially if they are old. I LOVE antique maps. Too bad I don't have any. Those suckers can get uberexpensive. (Look at the price HERE if you don't believe me) So I just stick to my National Geographic Maps. I have a lot. I keep them in my map table with map drawers, that my Mom gave me for Christmas last year. Like so:
When I was in college, I wallpapered my living room with maps. They were cool.
I wish I had a picture to show you of this, but I do not. At least not on Flickr.
Here is the map hanging up in my spare bedroom:
I need to hang up more, but I'm too lazy.
