You're singing my song, Dave.  I find it difficult to believe that so little work
or even careful documented observation has been done of feral honey bees in the
U.S.  I'm going to Yuma next week (and hopefully a few more trips there), and may
find if the isolated feral populations have bounced back - everything is blooming
now, but the last two years were dry.
