"Look, colt...If'n yer wantin' to make yer name as a bounty hunter, t'ain't none o' my business. But let me tell you this: Don't go after the Grey Mare. E'er since what happened to her daughter, she's been the Right Hoof of Death itself. Damn near fifty hunters been after her before, and only two lived to tell their tale. No gunslinger can out-draw 'er. No huckster can out-play 'er. No posse, be it for fame or fortune can kill 'er. Jus' leave 'er be. Otherwise, you can pay me in advance for your coffin."
