I have a neighbor who prefers his roof to his front porch. He takes a folding chair and straddles it on the peak of the roof. He then yells at everyone who walks past and gets a big kick out of the fact that they can't figure out where the shouting is coming from.
I've seen a few folks sitting in the garages here too Jerry, but everybody thinks they must not be from 'round here.;~) I don't have a garage but if I did it would be a mess I'm sure.
Wesley, there's a push by our town council encouraging folks who don't have porches to consider adding one on, for the very reasons you cite. We are a great town for walking too.
