Mr. Ball. That is right, sir. Here is the parkway.
Mr. Frazier. Right.
Mr. Ball. Here are the overpasses here.
Can you show us on that map where you think—will that map—can you on that map indicate the general direction from which you thought the sounds came from?
Mr. Frazier. Yes, sir; because we were standing right here.
Mr. Ball. Don't mark it up right now.
Mr. Frazier. Right. But what I am trying to say is we were standing down there, and back over here, this over here is more or less a knoll, and you can look over there and see this. You see this furthest left line that curved around here is the ones we take to come out on Stemmons Expressway, and this is a high knoll up here which runs where the tracks are, from standing there it sounded like it came from this general area over here.
Mr. Ball. Just mark on that if you can, if you can mark a source.
Mr. Frazier. This is where it is.
Mr. Ball. Mark a circle.
