Wow, JJFrank, nice one.
I'm also interested in this subject.
In some of my LD's, there's always a beautiful park next to my house (which doesn't happen in real life because there's a parking lot on the front and roads on the back). Once i went to that park and asked a DC the name of the park and he said the name of it and being in my city. But in real life i have no such park (or i didn't search enough). Next time i have to explore it more.
