Yes, around dead elm trees is the best... Also like said other dead or decaying trees, like ash, maple and oaks...South facing slopes early or places that rid themselves of leaves on the floor of the woods. Green is good...As the season progresses, areas of heavier vegetation, but those areas require a good schrooming stick and lots of patience..

There are lots of good books and forums, but it is best to find someone in your area that can show you the ropes. Even if it allowing them to hunt your ground to show you.. Pretty much guarantee they aren't going to take you out to their spots!!!
