VIDEO: 'Blue lining' with fly fisherman Chris Franzen

Chris Franzen calls himself a fly fishing junkie from the foothills of North Carolina, "pretty much a fish bum". On his days off, Franzen climbs mountains looking for the perfect "blue line." Blue lining means to take an atlas and look for the blue lines and find one with a nice gradient, hiking in no matter how difficult, fishing that blue line and striking it off the list or revisiting it for another round of fly fishing.
