I should have realized it was Dan but I wasn't listening through my loop (which I need for clarity)
For TV viewers they avoid the marquee by switching to the back straight camera but many callers do not like calling off the monitor
The marquee would obliterate anybody on course's view for quite some time unless they are standing to the west of the stand/bistro - at least Dan's elevated position lining up with the front of the marquee would help reduce his 'blind' time. From the usual undercover viewing area for patrons, the whole side of the enormous marquee is going to obliterate your view for some considerable time around the top bend.
I am glad I did not go (too many 'trots' races for me)
