I just arrived in Ottawa, Canada from Seattle, USA. I had sort of thought through exactly what Tim just described. I had a little notebook with me and was doing some calculations and design of a fractal compression algorithm. I started to think about El-Gamal and decided to look at elliptical curve algorithms. So, I pulled out my copy of Applied Crypto to look up some things and started writing things down. (BTW: I had Applied Crypto with me for recreational reading on the plane, I don't normally carry it everywhere I go.) Anyway, i got to customs in Ottawa, and they asked me if I had anything to declare. I immediately thought, "Should I tell them about the notebook?" I decided against it. How does export of intellectual property work? The other question they asked me was "Do you have any eggs?" I started giggling. **SARCASM ON** I always carry an egg around in my inside coat pocket. Who knows when you might need one, especially when in a foreign country. **SARCASM OFF** I don't know, I guess the question just struck me as funny.
