The only real way to tell the difference in man-made CCs and the real deals are by the details. Have any of those cropping up lately had any serious
analysis performed on them: Magnetic readings differing from the local baseline? EM interference with electronic equipment within the circles? High
pitched trilling noises recorded? Have any stalks been analysed under a microscope to see if there's any changes in the structure? Etc.
Personally, I think most of these CCs showing up within the last few years (at least) are man-made and/or added to ones found (before the public sees
them... In other words, defaced).
Why the UK? Well, as other posters have mentioned they are found all over the world. I suspect they are pretty evenly distributed, too. We here in
the US are a cynical lot, especially 'workin folk' who usually want to go through life with as little trouble as possible (ie-media attention,
gov't attention, ruin of business/reputation/respect, possible loss of familial support/love). We generally stick to the party line, which is that
all paranormal things are bunk, or if you're religious then it's from the Devil, (which would be something you wouldn't want your church going
neighbors to know is going on in the community, specifically on your land. It's a bad portent). Anyway, I suspect most of the CCs that are found
here in the US go unreported to national media, not that our media would take much interest in them anyway. We gotta keep our focus on more important
things like Britney's next impending meltdown or which American Idol has talent, etc.
BTW, Diplomat, if memory serves me you're here in Sacramento, right? Remember the Rockville CC? Only got a cursory survey, no real measurements
taken (magnetic, ultrasound, microscopic analysis, etc) yet it was sensationalised for a short time, then pretty much dismissed because a few
miscreant teenagers with criminal records 'admitted' to making it.
Supposedly the locals knew who they were because these teens were always in trouble with the law. Not many actually considered that they may have
been
coerced to lie about hoaxing it in a deal to have their criminal records expunged or lessened. So I guess the claim of an admitted hoax
is perfectly acceptable without gathering more data and/or having them show how they made it. You know, in court you can confess to doing all sorts
of crimes, but the burden still falls on the prosecutors to
prove that you actually did what you've claimed to, even if it's in their
favor!... Well, in theory anyways.
Also remember, another poorly made obviously hoaxed CC was found near Vacaville shortly afterward. But there was also another CC discovered by
another farmer
at that same time down the road, which didn't receive media attention or investigation.
One more point, followed by some musings. The UK has more population per sq mile than the US, so anything out of the ordinary will have a better
chance of being noticed. But I also suspect that the megalithic complexes found all over the UK (and Europe as well) might have something to do with
it, too. Perhaps the makers of the phenomenal CCs understand what these structures were actually built and used for, of which knowledge has been lost
to us through the centuries. Perhaps, they (extra-terrestrials, extra-dimensionals, extra-temporals, ancestors, contemporaries in the know) are
showing us what is right under our noses, in plain sight... giving us clues where to look and what to be looking for...
For instance, I read recently that the Rollright stones give off a steady
pulsing of frequencies in the ultrasonic range from 1-2 hours before
sunrise up through until a few hours after sunrise. Some have claimed various things like nausea, elation, syncopy, etc while standing in the circle
(The king's men) while this is happening. When a person is in the circle, the ultrasound stops. When they leave the circle, the ultrasound resumes
again (singing stones, indeed). We can't hear ultrasound, obviously, but it can affect us. What other interesting phenomena go on generally
undetected across the countryside? Piezoelectric effects produced by buried crystaline structures in 'sacred spots' through compressions/vibrations
from the sun's heating of the land in the morning? Yeah, I'm going out on a long limb here, but I think our answers may come indirectly from a
comprehensive approach. The next step is to come up with ideas and test em out, but no one seems to want or be able to do that, (myself included I
guess).
In short, Diplomat, they happen right in our proverbial backyard, not just the UK. Sorry for the rambling, it's been a long day and I'm exhausted.
Hope I made some sense.
