Curmudgeon,

I remember seeing crosses (not flowers) alongside rural highways where people had died in the 50s. This was in the west, so there might have been a spread of a common Mexican idea. The crosses did serve a purpose in the sense that if you saw a lot of them in a particular place, you might want to slow down.

‘Same for the highways on Oahu, Hawaii, back in the 50s.
