Yes Oliver the new dualling has made a big difference to the area.I live near Acle but use the A11 quite a bit.
Sure the HSE would have a fit if fuel was transported like in the old days but when i first raced at Snetterton 1959 much of it was concrete with grass growing in the joints and 40gal oil drums marking some of the coarse.
Still think the biggest mistake was doing away with the Norwich straight,although it reduced maintenance costs,it took away what made snetterton different from elswhere,to see Dereck Minter braking for the hairpin at the end of that straight was some sight
