Kind of a new guy.
Hey Bear,
I just found this forum not so long ago myself. What a lucky break that was! Like the guys have been saying; exercise and try to loose as much as you can before surgery. It will make the surgery go easier and it does set your mind for the big losses to come. My dad used to say that, "you never see a good rooster fat". I suspect that applies to bears as well. You've done the right thing and are about to go on an incredible ride. Good luck.
