I have never been before either Erica, apparently its quite popular. See http://www.calnemotorcyclemeet.co.uk for info. Calne is about 33 miles from Newbury Jimmy B, on the A4 between Marlborough & Chippenham in Wiltshire.
yes, looked it up - intend going mid morning if weather half decent - if you want to meet up and ride there - am meeting a client at lunch (who lives in Calne and isn't a biker but happy that it takes place!) but am free to wander before.
Weather permitting i will be there but will be stopping off at Swindon first to visit a relative. If i spot you Erica i will say hello & introduce myself !!
