Thanks Sam McMichael, deerhunter_w and GreyGoose. This IS a great place. I get so wrapped up in reading all the excellent info here, that I have to remind myself to post.
Kevsuperg, thanks for the offer. I have a surgeon that worked on my knees four years ago. He didn't kill me then, so I'll probably have him do the knee replacements, and the rotator cuff surgeries too. I've put it all off because I didn't want to miss out on any hunting, but things have gotten to the point now that I'm not able to hunt at times anyway, so I guess It's about time. I may set one up for after turkey season this spring and go from there. Thanks again.
Bob
