The first day on roads after the implementation of the Odd-Even Rule.
I have been to Peshawar once. I didn't have a visa for the city but sneaked in because I was desperately keen to track the Taliban. The year was early 2001, just before 9/11 awakened the world to the horrors of global terror emanating from the Afpak region. I couldn't quite get into the rugged wilds of the FATA territories but I did manage to meet a number of Taliban sympathisers in Peshawar
