How about 9.30?
On the slip road between the A47 roundabout and the A1 there is a cul-de-sac on the left. (The Old North Road) There is wide hard standing behind Armco there... Looks like the safest place to wait.
If you came off the A1 there you would see the place from the exiting slip road but best to go on to the roundabout and come back, rather than attempt a right turn at the converging slip roads.
