I am lucky actually to have a large porch and two patios.  I have the porch and a patio at my home, and a patio at my cottage. 

My love of screened-in porches (a patio) started many years ago.  My mom and dad had a patio installed on the back of their house.  This offered wonderful cozy summer nights and days bug-free.  This patio became the center of living during the warmer days of spring and summer.
