hi nebill!
your knee problem sounded like a real downer for a while there ,glad to hear things are on the mend.
I remember when a few years ago I lived for my road/cross country running . then i was beset with this pain in the knee, which eventualy required medical treatment.
The doc finaly advised me it was time to hang up my running trainers.
that devasted me for quite a while even leading to a deppresional illness.
then I turned to cycling as a replacment and of course it turned out to be a marvelous decision (probably enjoy it more than i ever did running)
The knee seems to hold up well to my cycling apart from a little paranoia with the nagging thought , what happens if my problem re-accurs on the bike,"perrish the thought" but touching wood all is well up till now.
