<strong>From Brad's Diary</strong>
<p>A developing country steeped in history, India is quite an experience. It intrigued me with its size and number of people - almost four times the population of the USA at one-third its size. And there are almost as many languages as there are states! It is a mix of tradition and modernism where serene villages co-exist with bustling metros. The people are quite friendly. From what I gathered, the society gives a lot of importance of family values.</p>
<p>Today, India is one of the most powerful economies in South Asia. India's economy is a mixture of village farming, modern agriculture, information technology and a wide range of manufacturing industries. Recent industrial and investment reforms have provided new opportunities for Indian business-persons and an estimated 100 million to 200 million consumers. India has a strong entrepreneurial class and a central government that recognizes the continuing need for market-oriented approaches to economic development.</p>
