Hey V8, sorry to hear what your going through--But thank GOD your still on this side of the grass, I've been rode hard and put up wet too many times myself.
All things happen for a reason-sometimes the reason ain't real clear. I started my journey back in 1986-Both knees are due for replacement/six disc either herniated or bulging/right shoulder tore up--some years I couldn't hunt as much or not at all-But I changed my style some and things seem to going better..
Good Luck--God Bless--And if you don't mind I will pray for you...

David
