LBS & crew, just read through this post tonight.
Hate to see how the varmints chewed up your boat!
Regarding the knee; hopefully you will be OK in the near future and not need surgery.
I have an uncle who had both knees replaced (10+) years ago and he is OK.
I have a friend and coworker who will need knee replacement surgery, but is doing fine.
(sounds like you).
Her doctor doesn’t want to do it until after 50 – she is OK with that for now.
Anyway, best of health to you
