Wow! What a fun day! - Day 12

Whenever people ask if we collect anything, my immediate response is "yeah, geek books". Don has shelves and shelves of them. He often refers to them and I always wonder why he needs so darn many on the same subject. At any rate, he has been studying up on a couple of subjects lately. Yesterday I came home from work to find this on my living room floor. Must have been one heck of a fun day! LOL
