There are a few animals I'd rather not see. Paul Boot tells of a mahseer trip to the upper Ganges which began with a 4x4 rides through tall reed.
Then the ground got very soft, so his group walked down to the bank, and fished upstream until midday, when they turned fish all the way back to the 4x4.
Right behind where he'd been standing, just feet away, were the tracks of a tiger where it had sat down on the sand, watching him. As they walked back, the group were chilled to notice that the tiger had followed them all the way from the 4x4, yet not one of them had actually seen it.
