We keep finding things to see and do in Karachi. Saturday morning and it was a trip with Khalid to the above mentioned exhibition. Small displays of concrete paving blocks and other construction items. About 60 stands. What was noticable was that there were 3 displays offering swimming pool plumbing and equipment. This is an interesting indication that the Karachi middle classes are looking to spend and indeed spend in new areas. I will be following this development closely.
