Late last season I hit a deer high with a too hard cast HP, so had a bit of a tracking job in front of me. I didn’t have anything to mark the specks of blood a few feet apart, and found myself having a hard time determining his direction of travel. After a bit of frustrated circling, I came across a scattering of weathered deer bones. I scooped up what I could find and used them to mark blood spots. I was amazed at how I could look back with my flashlight and they lit up and marked the line, even as soiled as they were. I eventually recovered the deer using a handful of the marking bones, and have since added a few weathered and cleaned up bones to the pile. I took a grinder to the ones that weren’t already sharp enough to shove into the ground and I’m not sure I’ve found a better tool for marking and leapfrogging along a blood trail. I’ve used tape and toilet paper but hate to leave that stuff in the field, which seems to frequently happen. Once cleaned up they are hard to miss with a light on them.
