Thank you. But my psychiatrist says I mustn't be encouraged.

Here's a forthcoming five day rally (Britain's longest) near Luton run by Polish detectorists (!).

PAS will attend to record finds on only one of the 5 days. It's the fifth such event. I went last year. It was on Crown Estates land. In other words officials acting for you and me had agreed to let them take the Queen's artefacts (and there were hundreds found) and our history back to Poland.
