If Old Glory is your sort of thing, the Barleylands Country Show an Barleylands Farm, Billericay is on next weekend (9/10 September)
It’s mostly traction engines (100+) but there is usually a load of old commercials, cars, motorbikes, tractors and plant, and the odd bus there.
Its well worth a visit, usually costs about a tenner.
great pics looks wet thou we went last year great weather and a brilliant day so much stuff in one place took us all day to walk round and night time was even better with the engines and fair
