Yesterday came down the A11, passed Newmarket services at 0900, just got on the A505 and joined a 5 mile queue, stop start, mostly stop. Usually park on the right of the airfield but it was coned off, [but they did open it up later], so had to go down to the land warfare end. Eventually parked at 1125. As NutLoose mentioned, weather not very good so left early afternoon like many others. When you come out from there you can only turn left. Not much use when you need to go the other way. Total of 188 miles, was it worth it? Not for me.
Hope people have better luck today.
