We're just back from a long trip to the U.S. and as we recover from friend, family and food-overload, I'll borrow a post from a local Cambridge picture of the day blog. See this entry for a pretty picture of some houses near us and a nice explanation for the biblical themes of streets in our neighborhood (We live on Paradise St and a colleague used to live on Eden St).
In case you don't want to see the picture and just want the info, here's the main point:
Orchard Street is one of several in the my area that have either botanical or biblical names such as Elm Street, Adam and Eve Street, Eden Street and Paradise Street. This is because they are all in an area that used to be the Garden of Eden allotments - small vegetable gardens and orchards grown by locals.
