Wow.
Some very good advice, and one or two absolutely ridiculous ones.
Frankly, I had a pretty rough night last night, so I'm not going to go point by point, but really... telling people to wear Burkhas in Istanbul is like telling people to wear chaps and six-shooters in Arizona.
I am essentially living in IST at the moment, and would not for a second hesitate to advise any friends or family to come tomorrow.
