Great time just after a rain...got to be there during the rain in order to be there just after it stops. I have seen some of the biggest bucks (for me) during rain or JUST after it stops. If it is a downpour I still may go but I prefer to take rifle/shotgun in that case.Late one August I glassed 4 bucks playing in a sweet potato field during a severe thunderstorm (I was in my truck). They did not pay the storm any attention and sometimes it would come down so hard I couldn't see more than 100 yds. in the field.
