Chicken’s Neck
Ah, Chicken's Neck! What an incredible spot on the South Asian map this is. With nothing to show for it but the lines drawn on the map after 1947, which separate this country from that and the other, the narrow strip is like the mouth of the tube of toothpaste that is India, squeezed out through this orifice, to exude into the eight states of the Indian Northeast.
At the very southeastern tip of Nepal is the town of Bhadrapur. Cross the border by wading through the shallow waters of the Mechi river, which drains the southern watershed of the Kanchenjunga, and at the village on the Indian side, catch the chhoti line (one of the few metre gauges still operational in India) which hugs the Nepal border all the way west to the Nizam's Lucknow. Or forego that option on this occasion and turn your attention southeast, where, barely two-dozen kilometres away, it is Bangladesh – Rangpur district of "North Bengal".
