Deer trails are to get from one place to another. They are not where deer move and feed. Deer will walk over every single inch of the land. There is not a blade of grass they have not stepped on but some can track a single deer---WOW.
Sorry, I need your skills.
I have found deer because I knew the land and where they go and have found deer by cutting circles.
Hunt a strange place without knowledge of travels and tell me you will track it, you surely hoax.
I find deer by knowing them and where they go, not by a turned leaf. 50 other deer could turn a leaf. OH, OH, a bent blade of grass I missed. When will you get real?
To find a dead animal without blood means you and others fan out and search. It is luck. To find a dead pig in a pig tunnel means it died in the tunnel.
I have tracked hundreds of deer. If you can tell me you can track a deer without blood you are crazy.
