Humor is another side of the festival. Comic dramas and street shows making fun of government officials are performed. People also roam the city dressed up like lunatics. Newspapers bring out special "mad" editions. From ancient ages people are allowed to demonstrate any critics this day, even when autocracy ruled Nepal.
In Kathmandu, the bereaved families proceed alone the festival route individually whereas in Patan, the participants gather at Durbar Square and then move out together. In Kirtipur, the Jatra starts from the night. Almost every won't sleep at night and on the Gai Jatra night a buffalo is sacrificed outside the Bagh Bhairav Temple. So I felt the Jatra as if it was a night-time Jatra.
The celebration in Bhaktapur is the most interesting one and I personally prefer going there if you want to see the true demonstration of Gai Jatra where there are tall bamboo poles, wrapped in cloth, and toped with horns fashioned of straw are carried around the city in memory of the dead. It seems like the whole city is taking part and all the city streets will be filled with the parade. It might be due to the narrowed streets there but all the city streets are found full on that day.
