If you read the Penumbra, you can probably find evidence of the Founders being obsessed with chalk marks of all kinds.
Every judge or justice to ever use the word penumbra seriously should have been impeached, disbarred, rode out of town on a rail and then presented with a bill for having the fire department there while their homes and possessions were torched.
And I can’t find a box of Crayola’s “sidewalk chalk” anywhere.
