Thanks for that under_exposed.
I was thinking more in terms that there was no large open space for several thousand to gather and of course if the landings are in an easterly direction that day a position beyond the railway line would not enable anyone to see much.
However, if on the morning it is apparent that the landing will be in a westward direction your suggestion is certainly one to consider.
We do seem to have had more northeasterly, southeasterly and easterly winds this year than is normally the case.
