last time I was in Pakistan was about 5 years ago. Over the preceding decade, I've been 6 maybe 7 times, including to Peshawar in the NW Province. The place is as dodgy hell, and terrifying as well. The scary thing is that all the hotels I ever stayed in have been blown up now. On one my earliest trips to Pakistan, I even holidayed there.
Strangely, I think though I was more comfortable working in Pakistan, than I was in some areas of Nigeria, like Warri in Delta State.
