>60 countries, with some having as many as 200 entry/exit stamps. my "passport" is 4 passports and several bundles of additional pages stuck together in something that looks a little like a james michner softcover. some countries I use one nationality to get into, some countries another (depending on visa requirements). I have a few old residential visas in the older parts, so I carry them around, and I have a lot of 5 year multi-entry that I don't want to go through the bother of replacing.
