You've been a great asset to the club and to thechipboard. I sincerely hope that things turn around for you. As for the knee replacement thing ... from personal experience and talking to others who have had it done... the universal comment I've heard is that virtually everyone wished they had it done sooner. Having said that, and not knowing your personal insurance status, most folks I've spoken to who had knee replacement procedures were covered by insurance to some degree or another.
Good luck to you Pam ....
