I concur on George. In fact, I first met a fisherman named Roop at one of George's classes two years ago. And like Roop after the clave, I was digging out my copy of the video this week.
At the risk of a hint of spam, George's website is www.whitemouseflyfishing.com.
He's got a new book coming out this year as well. Plain spoken casting advice. No gimmicks, and useful for every level of skill.
Driving away unwanted guests is a new application for the video. 'Til now, I'd only used it on my teenagers.
