The kitchen door opens to the inside and allows egress (I've always wanted to use that word) to the deck. It's on the sunny side of the house so even on the coldest days we can open it and sun shining thru the glass storm door heats up a small area. The dog and cat love it.
This picture was taken thru the glass the door, with some plants in the back ground. Patti Anne took it, I thought it was interesting, fly swatter and all.
