Can You Really Cook an Egg On the Sidewalk? | Wonderopolis
According to the American Egg Board, eggs need to be heated to a temperature between 144° F and 158° F to be cooked. That's why sidewalks don't make such great frying pans. Although sidewalks get plenty hot during a heat wave, they don't usually get above 140° F. They also conduct heat poorly.

I have no information about Arcadia. Apparently it is something in Greece.
