'L-lines' will be laughter lines, I guess. The archaeologists don't find much difficulty with the idea of spirit paths. There's talk of sacred geometry but the term superstitious geometry is more appropriate. Greek theorem one is 'the shortest distance, AB, between two points, A and B, is a straight line, A - B'. Avebury was probably laid out using huge triangles but they are far less obvious than the lines.
This Sanctuary to Silbury alignment will 'go live' on Monday, morning sometime, with the setting moon. So will other 'lunar observatories'. I should fillet out a list from Thom's data perhaps.
