I've thought about this many times, and as much as I'd love to see Egypt, I think I'd pass on traveling the middle east for now. One could argue, that I could step off the curb and be hit by a car, but that's a risk I'd rather take, dying in my own country. I don't relish the idea of being taken hostage, or being blown up in a market, in some eastern country.
Hopefully one day, the unrest will cease, and I will travel to these beautiful cities....if there's anything left to see of them.
