Hi Mangus... it's been a while since I have signed on to Ancient Worlds... I have been extremely busy lately. I just had a few things to add to the article on Coba. Sacbes and Sacbeob are the same thing... only that sac beo'ob or "white roads" is the plural of Sac Be (white road) in Yucatec Maya. Yaxuna (Green is it's house) is the meaning of the name of the other Maya site close by. Finally, "Nohoch Mul" means "Large Pyramid or Pile of Mounted Stones".
