The Nagaur Cattle Fair In Rajasthan takes place annually in January. It only has male calves (bachra) and bulls (bel), no cows. There are, however, female horses and camels allowed. People come from all over North India to buy and sell cattle. Some people come to 'dance' their horses and camels.
I met Mahendra Singh from Haridwar, Uttarakhand who took me around the fair and helped me by telling everyone I am Indian, so they would not hassle me. 09012837793 & 09058793325
