There are steam rallies all over the UK throughout the summer.
http://fleetdata.co.uk/events.html shows how many we have got to choose from.
There's always a good selection of vintage lorries, cars, bikes etc. as well as the steam engines.
Usually there's other attractions as well, dogs running round obstacle courses, birds of prey, that sort of thing.
This one had a motorbike display team riding over skips, so after they finished, I had a go. :P
