And then there is the Canadian's answer to; Now that we HAVE heat, how do we
keep it inside?

Several of our friends to the North have ingeneously cut some foil backed
bubble wrap type insulation available in various widths from you LHIC (local
home improvement center), duct taped the edges and seams and made a nice
outer covering for the canvas area of the pop top.  It is held inplace by
cutting the insulation just a bit taller and longer than needed so it sort
of binds against the pop top and the back top hinge area.  I'm sure someone
from the Great White North would share a picture.  This works equally well
in the summer to keep out the heat from the sun and you can still open your
roof vent.

We await pictures and instructions
