A Thing

I thought, was the object whose name had just slipped from my mind or my tongue could only manage to get out 'that thing' because the name of the object had somehow lost itself while travelling from brain to tongue.  

I found out yesterday, that there is A Thing in Sherwood Forest.  Yes, the forest made famous by the Robin Hood story.  A Thing, is Viking, and has nothing to do with their infamous rape and pillage of other peoples land, but was a meeting place where Vikings discussed law and order.  Civil Vikings?  No I didn't know that either.

Historical Societies and archaeologists are about to knock-themselves-out by rummaging around the forest surveying and recording A thing.
