;)Whatever the demographics are (& we'll never know) it would also be interesting to see how things vary by season. August, for instance, will see a huge influx of Spanish, English, & French.
.Another factor that probably encourages people here to interact & form friend/relation ships, is the fact that so few folk originate from GA, so there are no "grown up together" groups.
It makes for a diverse community, & I reckon it works well.
