Having lived in Karachi anything and everything is possible. Yes, I have riden in a Donkey cart, the leave springones, non-leave spring, and the racing carts too. I prefer the leave spring ones as they have more softer ride, other wise be ready for back breaker. I actually rode one when I did not have car in Pak and there was transport strike coming back from Hawksbay. I think me and the guys had more fun then the ride on the bus, lolz!
