Held in about 1981 in the Peterborough/Bourne area I think. I vaguely remember being a chair passenger with an old long lost friend of mine Chris, on his Jawa 350 outfit. Nice shade of red with the obligatory wafer thin chrome plating that peeled away as soon as water was mentioned!
Chris's good lady often came along and was a regular in the Miss Rally events.
The rest is a blur because as the saying goes "I was very, very, very drunk...".
There is a Rallery (rally gallery) of the 2009 Poser by Ted Trett.
