BTW, Pete, I got the same brush off as you about Stone-Burning but, like you I wrote again and their reply gave the impression they're taking us much more seriously this time. Perhaps they'll ask someone other than the programme makers, which would be a help.
The treasure Seeking programme, however, could be far more damaging. How do you complain about something before it's aired, when it will be too late afterwards? I found 2 MPs listed as having Ancient Site Conservation as part of their interests. One said no deal as I wasn't his constituent, the other didn't reply.
