last year was my first experience at tracking. I shot a bull with my muzzleloader and he didn't even let all 4 knees hit the ground, it was also getting dark, i called my guru, he said go to town, get 2 flashlights and LOT'S of batteries, track all night, its easier to track wet blood at night if it's dry out, than in the daytime. Boy was he right, the flashlite reflects off the blood like a reflector. besides, your not trying to sprint anyway, 3 hours later, found the 3 point bull. stayed up all night/next morning getting him out. Moral is, don't go home and dream (worked for me, but i'm no expert.) :p
