So really, when you see a sign for a subdivision that has he name and then "An adult community" in nicely scripted letters under it, what the hell is it supposed to mean? I've lived in this town for four years and still can't fathom what it means on the Lake Forest Glen sign. Still. And the worst thing is is that nobody else does either! I'm conviced it's one of the three: 1.) A retirement type subdivision where only adults can live. 2.) One of PTC's older subdivisions, and having lasted through the years has earned itself the title of "An Adult Community". 3.) The subdivision houses large amounts of XXX and porn underneath the tennis courts, hence the phrase "an ADULT community". Or it could be the headquarters for the secret PTC society where everyone goes to have fun after school and work and stuff, since they closed down our skating rink and our movie theater and built a target and a mechanic shop instead. What does anyone DO for fun here?!
