The famous pagoda at the starting line, with all the race officials. The area closest behind that high fence is for photographers. Notice the 2 rows of protective berms.
This infield road was straight in front of us. The tow trucks, ambulance and street sweeper were all parked there
With the zoom, we can see the other end of the same infield road. We could see the cars going by just under the sign along the white wall. I suspect that other side is 1 mile away. We were between turn 1 & 2 so that end is between 3 & 4 th turns.
