Southside, I live in Gwinnett county and there are MANY hills to choose from. I usually run to a 400m hill about 3 miles from my house. I do the same type of circuit that Arthur's boys did. People on this board (Glenn Mc, Nobby, etc.) have helped me to refine my approach.
This particular hill works well because it has a nice 200m flat area at the top and a similar area at the bottom.
If you want a complete description of how I do the cicuits, just email me.
