I like hunting in the rain too as long as it's not just pouring down.
One bad thing about hunting in the rain is when you are on a steep place and step on a stick just under the leaves and all that is wet and super slick...
You will find yourself on the ground right quick.
One day me and my partner hunted several hours on a rainey day... and we were all muddy and nasty looking.
He said this to me... We look like we have just been born out of the earth
If you ran up on a City Slicker while looking like that they would probably run off screaming... thinking you were right out of the movie Deliverance !
