How many of you nice people who collect casino room keys also collect non-casino room keys? If you do, do you collect only U.S. keys or do you also collect foreign keys? Just wondering.

I have broken the 400 mark on pizza keys and 1700 casino keys. I haven't counted my foreign and domestic non-casino room keys lately (although I finally did get them all filed away). Can you tell filing is not one of my favorite things???
