Hi Magpie,
Never been to the Malpass Yesteryear Rally, in fact I'll have to look it up.
The Shrewsbury event had dozens of traction engines, wagons etc both full size and scale. Everything from old cars to more modern [70's era], pushbikes, fairground rides; it really was a good day out. One or two trade stands not many but enough to keep a skip raider like me happy, managed to pick up a couple of bargains, one of which was a wall-papering brush ~~~ not so sure about that one.
One thing which impressed me was there seemed to be a lack of over the top supervision by enthusiastic marshals, a very relaxed atmosphere with some young people driving too. I have posted in the past re model engineering exhibitions and that somehow I don't always feel that I get value for money when visiting them, not so with this show, £12 well spent ~~~~ I like you have no connection with the organisers other than as a satisfied visitor.
Regards,
IDP
