just a small point, camp Site 1 location is not on maps but if you put OX16 1UT in multimap and zoom out one and look left one click you get Dukes Meadow Road ish
Hope this helps. - yes, yes, the stewarding lists explains how to get there from the M4o but if you want to avoid the centre from other directions it helps to plan. Especially it you are towing at rush hour.
