holy shnikees!
Where the heck do you put them? Do you have anywhere to walk around in your house? Have you ever considered building an igloo with all of your long boxes .
I'm at less than 100, just 1 short box that has all of my comics, TPBs and graphic novels, and I still have room for my bags and boards in there as well. I'm not sure if I could ever have more than a few long boxes. I do love reading comics, but reading them on my computer/tablet is just fine for me and then picking up important issues.
I am always acquiring new stuff that has to be inventoried. The majority of the long boxes are on shelves in the basement. The good stuff is scattered around in a few different places.
