We had a mustard gas store near us in the woods at Melchbourne, It was mostly burnt off after the war but some bombs, that were deemed too dangerous to handle, were left. The locals were quite relaxed about this but in the 89's the incomers discovered it's presence and you'd have thought the end of the world was coming. The MOD moved in and cleared it. Now they come back periodically to check the site and give the villagers a report on conditions.
