A Few Comments
Google Earth is a CPU-intensive application that may not perform well on all computers. System requirements are listed on their download page.
With a large number of sites on megalithomania.com the sites are initially turned off. This means you need to select the groups you wish to see displayed.
There appears to be some difference between Google Earth's idea of longitude and latitude and that recorded on megalithomania. This means that some sites appear up to 150m or so from their position on screen.
Icons with a green tick on them mean that the site's long/lat is taken from a GPS reading.
