Lots of people sit outside in the summer. The midwest has plenty of older houses with front porches and they are used. Granted, AC has changed a lot of outside sitting. I think the 'burbs tend to have more back yard sitting as visiting with neighbors passing by isn't as common.
Early morning and mid-evening are good sit'n times.
Well and places out here in Washington seem to be different that way
when I was a kid on the farm Ma and Dad would sit outside at night under
one of our front trees more than the porch, when I lived at the lake Whitman here had a front
deck with more square feet than the comfy A-frame home was always out there in good weather.
We have an enclosed front porch on our 100+yo home. It isn't heated, but it is screened with windows. It isn't large, but we have a glass table and chairs and 4 Adironack chairs, 2 face the other two, two are gliders. The nice thing is that is ISN'T buggy! Not at all fancy, but we spend as much time there as we can during the warm--ER weather.
Thanks for the porch complements. DH gets all the credit, as he is our builder. He didn't pour the slab though, -those guys were here pouring our basement. We wanted colored concrete, they wanted $1500 (just for the color).
While they were smoothing out the slab, DH sprinkled concrete dyes on it. He already had some around from making concrete countertops. The concrete guys thought he was crazy, with his psychedelic porch! It is fairly subtle though, and I really like it.
