Mr. SPECTER. You described the motorcycles which followed the pilot car. Were there any other motorcycles in the motorcade? Mr. KELLERMAN. Yes, sir; we had four other motorcycles opposite the back wheel of the President's vehicle, sir. Mr. SPECTER. Were those on both sides or on each side? Mr. KELLERMAN. On each side; two on each side. Mr. SPECTER. Were there any other motorcycles in the balance of the motorcade? Mr. KELLERMAN. Not that I recall. Mr. SPECTER. At what speed did the motorcade proceed at the various times en route, say, from Love Field down to the downtown section of Dallas, Tex.? Mr. KELLERMAN. As we left Love Field, the driveway from this apron on the field was sort of a winding thing, and there were many people that gathered on the roadside to view him as they passed. I don't think we traveled more than 12 to 15 miles until we left the airport apron proper. Mr. SPECTER. Twelve to fifteen miles per hour? Mr. KELLERMAN. Per hour. Mr. SPECTER. Yes. Mr. KELLERMAN. Then, as we were in the opening between there and the city limits of Dallas, we could have gone 25 to 30. Mr. SPECTER. What was the size of the crowd at that specific point? Mr. KELLERMAN. Nothing in between then until we hit the outskirts of the city. Of course, then you got into a residential, a school, area where all the people were out on the curb line. Mr. SPECTER. What was the speed when you reached that area? Mr. KELLERMAN. Then we would reduce the speed down to 15 miles an hour. Mr. SPECTER. What is your best estimate of the minimum speed traveled until you reached the downtown area? Mr. KELLERMAN. We could have been going 25 to 30 at several times, sir. Mr. SPECTER. What were the crowds like in the downtown area itself? Mr. KELLERMAN. A lot of people. Mr. SPECTER. What was the speed of the motorcade when you came into the downtown area? Mr. KELLERMAN. It would be reduced down to 10 to 15 miles an hour, sir. Mr. SPECTER. Were there any unusual occurrences en route from Love Field until, say, you got to the downtown area of Dallas, Tex.? Mr. KELLERMAN. As we were on the outskirts of this town and apparently reaching a crowded area there were a group of youngsters on the right side of the car curb-line-wise, that had a large sign, oh, perhaps the width of the two windows there, that said, "Please, Mr. President, stop and shake our hands," and he saw this and he called to the driver and said, "Stop," he said, "call these people over and I will shake their hands," which we did. The entire motorcade stopped. I got out of the car and stood alongside of it while these people were right up on me. The agents who were on the followup car, all around it. And then after a few seconds he said, "All right; let's travel on." Mr. SPECTER. You say the agents in the followup car moved up at the stopping? Mr. KELLERMAN. Always, sir. Mr. SPECTER. Specifically, what did they do on that occasion?
