Well, my first love is First Edition hard cover books. I love to read so why not have the first, right? I've discovered that while I can't read everything, these books certainly look impressive on my bookcases, even though I only have around 400.
I also collect Green Bay Packers football cards. I've noticed that it's much easier to store and look through my card collection than it is to enjoy my comics. Even if I only have a few mintues, I can pick up a binder and look through a few cards. I like that.
As for comics, I'm learning that it's a fairly ugly hobby and not easily accesible. I mean, how many ugly white cardboard boxes do you have? How often do you get to read or enjoy your comics? It's just not as easy as the other collections.
