I'm saying AMEN to the idea of a shelf gizmo that is braced inside the house- screwing into the wall. The ones I put in my father in law's house I actually built a frame on the outside sill and into the inside like a shelf- 2x4's and plywood, gasketed with insulation. Otherwise... well, people outside need to DUCK !
