I regret not getting clearer pictures to zoom in and see the words on the instruments but I felt the need to be discreet as I was just walking by, these ocean-front home garages are rarely/NEVER left open unattended. What is this mystery chamber?
One more different angle picture in the comments, you can see the seating bench in the chamber.
Heehee.
I wonder what laws I’d be breaking if I did that.
I always err on the side of caution: “If it’s not yours, don’t touch it.”
