I haven't hunted 63, but I have hunted 63A and 67 on the river bottoms. I have had the best luck finding a well used trail and setting up and having a partner brush all the way around you. I have never shot anything, but I have always been the brusher. We have been chasing the whiteys, but have ran into a few muleys also. I will be in 63A saturday trying it again. Best of luck to you.
