[RE-wrenches] Snow-frame damage

[Blake Gleason]

In my photo (not the greatest - sorry!), the middle modules have unbroken
glass.  The one on  the left has a severely bent bottom frame section, and
the one on the right has a completely failed (torn away) bottom frame
section.  The other modules in the photo have failed bottom frame sections
AND glass/laminate creeping out through the (missing) bottom frame.  I
believe the glass on those two shattered after it started creeping out of
the frame ...
