Congrats on pulling that tag SnkyHuntr..!!
Been on the San Juan a couple times in late July just to see the velvet bucks. If your grandfather can pull a bow, I'd say he will get a great deer...
PM me if you would like some direction. I've got a video of an evening trip my father and I made there a couple summers ago. Could have killed a few good bucks from the road with our bows... I had the video on Youtube, but when I changed Google Accounts, it was deleted and I just never uploaded it again. I could re-upload it to share...
