Montana Fishing Guide has this to say.

My name is Ron Granneman. I Guided on the Big Horn river in Montana for 20 seasons having retired from guiding in 2001. I was inducted Legendary Guide, Year 2000, Freshwater Fishing Hall of Fame. In the last 20 years I have spent close to six months each year flyfishing both the North and South Island of New Zealand and have fished over 180 different rivers and a fair number of lakes on both islands. I believe it was in 2002 when I receive a call from a friend asking if I would assist Brad Kastner and share my knowledge of New Zealand to help him on his first visit there.

20ll marks the eight consequtive year Brad has made it to New Zealand. I can honestly say that I can not imagine any avid flyfisherman acheving the success at catching large numbers and size of trout that Brad has done in those 8 seasons. Brad’s enthusiasm at tackling the mind boggling array of trout waters and willingness to put on the physical miles has gained him a reputation that would be the envy of the most keen and accomplished angler. His success at catching many large rainbow and brown caught the attention of New Zealand Fish and Game personel who requested he testify, along with two other very experience Southland fishermen, in order to qualify a protective conservation order on one of Southlands top brown trout rivers. Brad’s enthusiasm for fishing, his magnetic personality that seems to light up a room when he enters, along with his uncompromising honesty makes me confident to give him a well deserved and unqualified recommendation to anyone contemplating using his services.
