I live in Gwinnett. I have been at this hobby for a long time. Hep, hit this issue squarely on its head. I will work to add to this.

For many areas in the western portion of the county one would not want to be over there.  I have lived in Gwinnett twice, from 1988 to 1990, then from 1994 to present.  I grew up elsewhere and became very experienced in "urban blight". I never seen an area turn for the worse so quickly as the western portion of Gwinnett. I can remember when Meadowcreek was considered a good and safe high school, now the kids elsewhere in the county call it "gettocreek". So long story short, you don't want to be on the west side.

Elsewhere, the police are quite active.  The community, though as stuck up and redneck as they are, do not want this going on there. Being politically mindful the DA and others make a point to keep folks happy. Stings abound.

Now sometimes, one comes across a good one in Norcross but its rare.  I saw one and wrote a review. She is trying to get to Perimeter as quickly as she can do so.

Yeah, driving from where we are in Gwinnett, over the loop and into Perimeter is a hassle I admit. The results I have found to be worth it.

Good luck.
