Book excerpt: Many of us have had dj vu experiences during our lifetime, that inexplicable feeling that we have lived these moments before. I have had many moments like this while in the Yucatan and have read that several others have experienced the same feelings there. I have experienced these dj vu moments at Boca Paila, Quintana Roo. Certain events unfolded there that were extraordinary. I am convinced that there is an entity or spirit at the Boca that is very friendly to me. I was reading Forest of Kings (Schelle and Friedel) one day and when I read a passage that mentioned a vicious war between Chichen Itza and Coba. The hair on my neck stood up. Of course, I instinctively already knew this.
