found this recipe that claoims it can be used to track or trail the deer's blood trail. it is made up of jsut hydrogen peroxide and food coloring and that is it. it claims that it will bubble up on blood when it comes in contact with it and even dried up small drops of it. which it seems kind of logical because when up put hydrogen peroxide on an open wound it bubbles up so i am willing and anixous to trythis one out this year!
bad day of hunting beats a good day of school or work anytime
