The Marshall-Petaluma road junction is invisible around a bend as drivers approach from the south, and some speed up as they perceive that they have passed Hog Island.
Keep the grass mowed on the MP junction corner to ensure that drivers exiting the MP road can see.
The hillside vegetation opposite Hog Island on the highway blocks vision going north, and should be trimmed regularly. We think Caltrans is responsible, though it's possible we can ask for help.
Move the "T" sign at that location so it is more visible (see image )
Fix the broken signs (e.g. the posts opposite the MP junction have been driven into and are broken)
