Don't be fooled as rain can enhance the scent as well. Sure it will disperse but remember, my Axel tracked a blood line that was 14 hours old and it rained all 14 hours. It only took him 1 hour to travel the 400 yard, 10 oz. of blood trail.
He was only a pup when he did this, now imagine the nose of a wary whitetail!
HOW does the rain "enhance" scent? It's rained 5-7 inches here in the last 24hrs. We also don't leave blood (hopefully)
. Human scent.....a little rain?? Gone in hours...and a very few if I were a betting person.
How much rain we talking about on that blood track, Rob? Interesting.
