First of all in all the years your grandpa has been hunting was he any good at it? If he was then I wouldn't say anything. Even if he wasn't it probably will not do you much good anyway. Most people once they have been hunting a few years are pretty set in their ways, let alone 60 or more years. You can talk until you are blue in the face and chances are he will still do it his way, or just not do it anymore at all. He will most likely tell you he is old enough and been doing it long enough to know what he is doing.

If he doesn't want to kill anything I say have everyone chip in and buy him a really nice camera and let him have a blast with it. The nice thing about the new digital cameras is you can take a ton of pictures with them. Might take him a while to get used to it, but I think he will like it. And think of all the fantastic memories you guys will have from it.

If your lucky and your grandpa is healthy you might have another 15 years or so to share with him. But at his age next year or the year after could be his last year hunting.

If it bothers you a lot my advice is to encourage your grandpa to take hikes often in the woods, and go with him if you can. Spend as much time as you can there during the season and the off season. I honestly believe the more you are there the more the deer will get used to you and the less of a problem it will be. Where I used to live we had deer come right in our back yard and bed down. Deer are very adaptive and not really that smart honestly.

Good luck with whatever you decide.
