Today I finally bothered to take a photo of the hobo/tramp/gypsy markings by the Algiers side of the ferry across the Mississippi.

Looking at the first few google hits for "hobo signs" informed me that the "X" means "OK" and the slashed circle something like "A good way to go", but I'm still ignorant about the rest.
Any epigraphic help out there?
