I have noticed over the years that I will get a bite, I fish for channels, when a boat comes screeming by or a heavy truck drive by in close distance from me. Even noticed it with a train track close by. I've always considered the right way is to be quiet while fishing. Has enyone else notice anything like this? I'm in no way suggesting to make a bunch of noise to attract bites either but does the sound waves or vibrations make the cats grab and run more.
