A suggestion for your trip back through Pakistan...if you go to Islamabad, try
to go to the excavations at Mohenjodaro (3000 - 1500 BC)...well worth a day of
your time. For museums, Lahore and Karachi are fascinating...all hot and dry
in the summer, but observing the marks of different civilizations makes the
trips more than worthwhile.  Have a fine adventure!   Jane Glaser
