Diving is not important enough for me to do anything but quit if I even had
a hint of a PFO. You really have to be kidding. In fact, if I even got bent
I would likely quit. If I had do dive with and around the morons you the
rest of you guys dive with, I would have quit a long time ago. Thank God for
the WKPP. The smartest thing I ever did.

Trey, with all of this discussion I haven;t seen your thoughts on possible
repair of the PFO. I''ve seen limited information on possible repairs. Have
you seen or do you have any insight on how that goes?

thx good stuff,
Harold
