Oak Creek Tags Need Some Advice !HELP!

I could youse some advice my wife & I both drew tags for oak creek even though we have been trying to draw thease tags for a long time when we studied the draw odds I told my wife that with her points she could have a good chance to draw draw a bow tag and I would have a good chance to draw a muzzy tag if by chance this would happen it would be the perfect set up for the season. Well it happend we drew but after the couple of scouting trips in the past two weaks she is unsure she can hunt up high were we are told the bigger bucks are or will be in August, she is a great shot & practices often but has a bad knee. We both OLDER! but I can Hunt the top no Problem Should I Talk her into turn the tag back in and weight for a rifle tag another year or try to encourage her that we might find her a buck in the lowers, I want this to be a good experience for her she likes the bow hunt the best because it is warmer. HELP WHAT DO I DO!! THANK YOU olddenny
