I lived in Irmo for a few years and really liked that area. That area and the Chapin area are really nice in my opinion. I can't say how good the schools are since I have no children. Both sides of the lake seem to be nice as far as I could tell. Chapin and Irmo are convenient for I-26 and the Lexington side is convenient for I-20. I-26 is closer to most of the shopping including Sportsman Warehouse and quite a few other tackle stores. As far as heat & humidity, as opaleski said that's everywhere, as is crime & poverty. I don't know how good the fishing is in Md but there are a lot of excellent lakes in SC.
