Mr. Specter. When the President's automobile was proceeding in downtown Dallas, what was the ordinary speed of the automobile, based on your best estimate?
Mr. Hill. We were running approximately 12 to 15 miles per hour, I would say.
Mr. Specter. I show you a document which we have marked as Commission Exhibit No. 354, which is an aerial photograph identical with the photograph already marked as Commission Exhibit No. 347.
(The photograph referred to was marked Exhibit No. 354 for identification.)
Mr. Specter. I ask you if, referring only to Exhibit 354, you are able to identify what that scene is.
Mr. Hill. Yes, sir; I am.
Mr. Specter. Are you able to indicate the route which the President's motorcade followed through that area?
Mr. Hill. Yes, sir; I am.
Mr. Specter. And what does that scene depict—what city is it?
Mr. Hill. That is Dallas, Tex. It shows Main Street, Houston Street, and Elm Street.
