We are excitedly packing and rearranging the indoor topiary and landscaping to make it easier for our neighbor to manage watering this jungle of plantlife.  We'll be in Istanbul, Byzantium, Constantiople, and PfRC will be taking a short sabbatical.  I have read that the Turkish people have a slang designation for Germany--exonyms are a challenge, Deutschland--Frengistan or Frankistan.  I feel I have barely cracked the guidebook but we have already an overwhelming amount to explore.
