RE: blood trail
Good tips...I carry paper towels or tissues to mark each place that I find blood...Most properly hit deer with a bow go less than 100 yards...If you lose the trail these markers show you which direction the deer is going...You can use these to show you which direction to continue...To be honest, this is a last resort, most deer don't stop bleeding, we just want to follow too quickly, slow down, take your time, there is still a trail you just have to have the patience to find it....
This is another reason to be very selective in shot selection, don't shoot at any deer that is in range, wait for the proper angle and be positive that you can make a good shot, in doing so, you will know that you hit the deer properly and this gives you the confidence to keep looking until you find the deer...Good Luck
