I'm sure most people have heard of rescue archaeology.

With all the housing developments taking place in the SE, has anyone thought it might be high time to record crash 'sites' in Kent, which unless I am mistaken, the whereabouts of which are now becoming lost (especially as interest in excavations for now at least seems to have gone abroad)?

If indeed I am mistaken, where may I find this information myself, these days? (Or am I too late).
