I live in Cumming, off exit 13 in South Forsyth. i have seen some of the negative talk about "speaking english" and whatnot. Yes, there are a lot of technology workers in South Forsyth and a large Indian population, but that has it's advantages. Our schools are top rated in the state, and we have lots of great restaurants and places to hang out like Halcyon, the Collection, etc. It really depends on what you prefer to get out of place that you live. I have about 12-13 parks within a 15 minute drive of there, easy access to Alpharetta, and close to all grocery stores, shopping, etc.
Regardless of where you want to live in Forsyth, we have the best Sheriff's department, and very low crime rate compared to neighboring counties. I would highly recommend exit 13 and 14, but I know it isn't for anyone.
