Tnstonefly - That's a great video and one that I can truly identify with since I also have PD and love to flyfish more than about anything else . It was great to see him try time and again to hook a fish and not give up, because the disease can be very frustrating when doing things that you used to be able to do easily are much more difficult to do at all. Even making a decent cast is an accomplishment some days. I could go on and on about what it does to limit what you can't do, but it all is worth the effort when you have a "tight line", cause nothing feels as good as having a fish on the end of a 9 ft flyrod.
I've not caught a trout like the oe in the video, but Lord willing, that day will come.
