LF,

Your article got me thinking about something I had read a few years back. Turns out Orvis was thinking the same thing, and they built just such a course in Bend, Oregon adjacent to one of their stores. The course has been open since 2008, and has hosted a fly casting competition in 2009 and will again 2010. This course unlike the one created by Lefty is free and open to the public. It is designed along a golf course motif and so has "holes" (18 of them), and scorecards which are avilable from the store. More information in the links below.
