This is your beloved Question-Man. I have Two (count 'em) Two questions---one of which may be shell related.
  1. There's this thing we find on the beach. It is shaped like a doughnut with a bite taken out. It is about 6 inches across. Rubbery, thin, dark green. The part toward the center is raised. There are lots of them on South Carolina beaches. Egg cases? I don't think so. But I've been wrong before.
   Ideas?
  2. Non-SR: Tank trucks have this diamond shaped thing on the back with a number. "1203" stands for gasoline. But what do other numbers stand for? I'd like to know the difference between a tanker carrying milk and one carrying Sulphuric Acid. How does one find out? The library wasn't very helpful. Why is it a secret?
