Thanks to your FYI I did go to that seminar. Well worth it. I didn't have time to stay and buy the a book by speaker Kent Cannon, but I did find his web site and ordered it and got it in 2 days! I already had a Kokanne book, but not one with local knowledge.
All his techniques are used in local waters like Detroit lake, Wikiup, Greenpeters reservoir, etc, so if you want Kokanne, his book is a must.
