>If I do leave them on, I really like Randy's idea of securing them to the
inner covers.

I believe that it was Bob who suggested the rims.  I know of other beeks
using permanent top rims, including some in Canada, Australia, and some
large commercial pollinators in the US.

I personally am confused about the whole top entrance question--both summer
and winter.  Reports are often contradictory.  So much appears to depend
upon local humidity and temperatures.
