I dont want to give anyone ideas. .... A while back some American Indians toured Australia with local Aboriginals. Local Anglo New Agers went along and started 'charging' crystals and buring them 'on the intersections of ley lines'. Some Aboriginal elders were very upset ... it's a big rave why ... and might not make any difference in another country.
It all leads on to another longer story (I think I wrote around here somewhere) about Aboriginal crystal technology and the dangers of people who don't understand what they are doing mucking around with it.
Some of them don't even like others using a didgeridoo. White people run around doing crystal didgeridoo 'magic' with out any concept of what their actions mean to the Aboriginals.
To reverse it, it's a bit like a tribal aboriginal walking around inside the control room of a nuclear reactor, pressing buttons and pulling levers; "What's this for boss ... what this one do?"
That's why they keep their sites secret and their 'technology' secret .. to interfere with it can disrupt the control and warning system they use for storms, floods, tidal waves, etc.
