Are we to assume Monarchs are too stupid to find other sites?  All this talk
and number-crunching is dung in the real world. What did house sparrows do
before there were houses?  Barn swallows before barns?  Ratings, ratings,
rantings...  So what?  You can't tell me such a successful insect couldn't
adapt.  We'll destroy ourselves before every resource is depleted.  Go to
the Mexican Government.  This whole Monarch business is not only moot, it's
completely boring.  cb
