Changing to the other side of London, but keeping to the same discussion is there not a North-South route on the West also. Can't remember the details but it involves some pretty low altitudes......1500ft springs to mind and over Ascot?
That sounds more dodgey that the LCY - Lee Valley routing although my half mill shows less yellow in this area. Anyone know the details of this or am I talking cr@p??
