I've been comuting by bicycle since the mid 90s and totally car free since 2011. In that time, Atlanta has steadily gotten better for cyclist. I must have started a trend
I'm not sure the last ten years are unique. But cycling here continues to get quite substantially better. In the last couple years we've had the beltline trail open, and a number of bike lanes and other work. The city has big plans for the future and specific targets for 2014. Our mayor wants this city on the top ten bicycling list (can't recall who's list it is exactly but some independent organization).
