Al, you mentioned catching fish while a Bobcat and truck were making noise and causing commotion nearby. I too have had a similar experience while fishing the Whitewater River near Sedgewickville, Mo. A county bridge was being replaced last summer over Whitewater River hence several large gravel dump trucks and front-end loader were in constant motion near a very productive pool. While I expected the worse, I've never experienced better fishing at this particular fishing hole just a few yards away from the constant motion/noise of the equipment. I've always wondered if the noise/commotion/vibration of the equipment caused the positive fishing activity. Another similar experience had a landowner high decibel mowing/blowing his clippings plus I assume insects into a 30 yard span of Whitewater River creating excellent fishing, especially goggleye, in that particular instance.
