As long as there are no serious accidents requiring a complete shutdown at some time then 7pm traffic is not much differant than 8:30. Since the end of last summer i've worked in Buckhead and lived in G'ville, 2.5-3 hrs a day driving, 49 miles each way. Luckily i now live in midtown...10 minutes to the office w/ traffic and no more 2,000 miles per month just on commuting.
