How do you describe Pakistan...the British colonial legacy, the Sind Club and it's "deep-end" with the snooker tables where women weren't allowed and you had to "dress" for dinner, the muhajirs who came up from Bombay after 1947 with their sari's and sophistication, the small Christian communities..especially the Goa'ns. We would go out on a "bunder-boat into Karachi harbor at the time...get drunk...all the few Europeans in the town ....while the bunder-boaters made curry out of the crab, mussels, etc. we caught.
Pakistan has grown since then. Still it has the Indus (and in Sind it's more like the Nile flowing through a desert)... And it has the Delta, the Thar Parkar desert. It is the sub-continent. and from the passes up above Gilgit to the Baluch desolation it's worth seeing.
The legend goes when Napier against orders took over Sind Province for the Brits...he sent a telegram to London saying "I have Sind." The Pak insult for a Sindi is "If you come across a cobra and a Sindhi at a crossroads, shoot the Sindhi first." and the homily, "buy a Pathan, lead a Punjabi, treat a Baluch with respect, shoot a Sindhi." (The Bhutto family were Sindhi)
I could be tempted by your trip gentlemen...but might be back there anyway at that time. I can post dozens of photos. It's worth consideration.
Just be careful in the Pashtun areas. And Karachi is about 1/4 Pashtun, 1/4 Baluch, 1/4 Sindhi and 1/4 Muhajir. The Muhajire control the place. very moderate though they have their militias.
"Shooting" at the time was British-like gentlemanly with servants and beaters - I'll explain it later. Take your golf clubs....they were sand courses in 1975...not now. GW in Islamabad, 2007
