Bob Wyatt is the man behind the Deer Hair Emerger fly, the books Trout Hunting and What Trout Want and has written a number of articles in magazines too.
He has lived and fished in Canada, Scotland and New Zealand where he has had the chance to observe the behaviour of trout especially with a dry fly.
While researching this podcast I realised that as someone who has read both books that he has had a huge impact on my approach to fly fishing.
