People's yards can easily be recognised by the coral gravel scatters around the houses. If you need to cross a yard, please ask the people for permission. So please do not bring any alcohol. However tempted, do not pick up any round metal objects or ammunition. There is still a great deal of scattered live ammunition about which may, if improperly handled, explode to harm limb and person.
Ammunition tends to be more concentrated around and in gun emplacements.
Please take care if you go exploring unaccompanied by a tour guide. Do not collect any artefacts. The next visitor will be grateful that you left them there.
