At our layout (The Mendocino Coast Model Railroad & Navigation Co. in Fort Bragg) we have installed a sound card and speakers that enable the layout operater to stage a thunderstorm behind the diorama we call Three Chop Ridge.
If we didn’t have the sound effects already I would suggest that we use the sound from this vid. To get the full effect close your eyes as soon as you press the “Play” button.
The vid is of the Angel City Choir. My daughter Annalise gave me the heads up.
