Sorry, having far too much experience w/cancer lately myself (i.e., wife's Ovarian cancer), I was one of the guys telling John not to delay and get his butt into surgery ASAP. However, it sounds like he went out doing what he loved most. Time spent in the woods this season w/him was a precious gift. Although I was asking him to get it taken care of right away, I'm not sure I would have done it any differently myself.
Prayers & Condolenses to you and your family.
