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!

I've learned for tracking purposes that rain or moist air is the best time to track as the scent is laid down heavy on the ground and enhanced. Our dogs have been known to find deer 48 hours old.

I've understood that human scent can stay on the ground, under a stand for days on end.

The worst tracking is dry cold air and scent is dead in it.

I've always known this rabbit hunting/beagling. A moist morning, the beagles would be 10 fold better than cold crisp dry mornings.
