Upstream of the obstructions in the photo, there's a hole five or six feet deep with strong current, where trout can hug bottom where water is slack. I swung a black bead-head Woolly Bugger through repeatedly, fly casting it into different positions to get different drifts for 15 minutes or so. Then my wife and I left for dinner at Walpack Inn.
You'd see a shot of trout, had I caught any, but even a stint as short as this one, and as absent of action, can be a highlight.
