For thrill-gangers, that's not easy, of course. Your colors mark you, and anyone who's seen them knows the likely places to find you. To avoid being found, you've got to hole up somewhere else. With a gang, that means ducking into another gang's territory. Which, in turn, means doffing your colors-which no self-respecting ganger is going to do willingly-so that the gang whose territory you've entered won't serve you up as an object lesson to anyone with territorial ambitions.
