st: RE: merging data sets
Your first scenerio looks like an append problem (adding new records to
the bottom of a data set--increasing the number of observations) while
the second looks like a merge with a "by" variable, park name (join a
record to the end of another--increases the number of variables, though
you may add some observations as well).
