Anything expensive I'd ever dig up probably belongs to the queen anyway. *le sigh*
It's my understanding that http://www.detecting.org.uk/html/Metal_Detectors_The_Treasure_Act.html is one of the most lenient pieces of metal detecting legislation in existence, and favors amateurs more than laws here in the states when it comes to antiquities. The Act specifically covers England and Wales, so the laws in Scotland may differ...but I'm sure there are similarities.
It's just a thought. There are many amateurs here who visit the UK for the very purpose of detecting, and the laws are likely more stringent for 'yankees'. heh heh.
Also @electricRubber, the link to the Ship breaking yards in Bangledesh was very interesting.
If anyone uses GoogleEarth, there are great swaths of ghettos to be found in places like Rio de Janeiro, Brazil as well as New Delhi, India....not exactly wastelands...just ghettos.
I find them interesting viewed in GoogleEarth. Also the current images in Haiti show the tragic tent camps from the earthquake there. What a mess those people have experienced.
