It does?  I am aware of no such requirement.  I thought we just stipulated
that breakfast was in LA and lunch was in San Diego?

Two events may or may not occur at the same location (same location defined
as the same spatial coordinates at the two different times as measured by a
*single* frame of reference. Note: this definition is frame independent).

I disagree with the above statement.  The theory of special relativity is
fully capable of handling the situation of two events occuring at different
locations.  (location defined as above).
