God Bless him and he has.
I had a liver transplant 14 years ago my Dr was a deer hunter. He told me to hunt as much as wanted to and he enouraged me to. But he made me promise not to use a climber. My diaphram was cut and I lost alot of upper body strength.
So here I am 14 seasons later and no more climbers. It doesnt bother me one bit as long as I get to go to the woods and see a deer I am happy. I shot 3 nice bucks 2 years ago and have not pulled the trigger since. I can honestly say I dont care whether I shot a deer or not. As long as I see one from time to time is enough to recharge my batteries.
I pray your Dad continues to recover and has a very special Christmas. I got a feeling he is going to
