This is the line that skirts the left side of the plaque without touching the plaque. Ya might get a ticket if you touch it. Starts a bit stiffer on smooth granite, then the low angle helps to make the upper part mellower. Kinda neat to check out this ancient plaque up close.
Location
Just left of the big plaque.
Protection
TR. Can use a #3 & #6 hex & an old bolt off to the left.
