Thank you for  Around the World today. Today, we are in Pakistan. In Pakistan, you can find some . In some parts of the country, many trips are not comfortable. Most people go from one town to  by bus. It is a good idea to take enough food and drink with you because it's not easy to find restaurants or shops  the way. The buses are usually crowded. Many people sit on the top of the buses and it is very hot in summer and cold in winter. But one good thing is that you can buy things , so you can save some money. You only pay what you get!
