Lets see, to put my free time in 1 post, I enjoy....watching documentaries about nearly everything, photography (all of it), playing video games (mainly just Sports games now-a-days), work (I'm a "fetcher"/intern, but I love it) and playing every sport out there, even if I suck.
I've lately become 'obsessed' with the Kennedy family, but not because of their political leanings. More because of their "story".. I've probably watched 4-5 documentaries about JFK and his family and have read 2 Kennedy books in the past yr.
In response to the freemasons answer above, that interests me too. I don't know a whole lot about them, but I passed a temple here in Palatine the other day which prompted me to at least look into it a little.
