I’ve been to Persia a few times.  It’s one of those really old places.  Well, all places are really old, but Persia’s been held by a serious civilization for thousands of years.  Means their cities are some of the oldest on Earth.  Real good places to search for information about our past.  You’d be amazed what you can find when you start looking.  Persia is one of the places we still do.  We’re always finding something new.  Well…old.  Whatever.
