I do not think so
Need to spend some time with Miss Daisy tomorrow.
Thanks for the comment - still learning to take "go-fast" pictures, much to learn.
I can't answer the "turn 6&7 wide line" question. I ride a HD Electra-Glide. My line would be much wider than any shown in these pictures. My line would probably be in PA or VA!
The line of the A group and B group riders seem similar, right - the B groupers follow the CRs so that explains that.
However, what I observe is the difference in body position between the two groups or riders.
