I'll share another book I read a few years ago. I felt is was so profound - how all the old celtic roads in Europe are aligned to the solstices. This was new to me. It may be old news to the rest of you, but I sure feel it supports some of the conversations I've listened to over the past 7 or 8 months. Joy! Note that the reviews on the book and his conclusions are mixed. : )
