I'm curious about something I saw last week while in Orlando. When driving down the highway I saw numerous backyards with what we in the midwest would call a screened-in porch. However, they are not built so large here. The screened-in areas sometimes seemed to encompass the whole back yard, but most were the width of the back of the house. Is this just something that is popular in Orlando, or is there a particulare reason why the screened-in areas on most homes are so large?
