Ahh. Commuting in the most bike unfriendly city in the US. It's an adventure. People ignore speed limits, pass too close, and generally drive like maniacs. None of that will stop me. Cruising into work on my bike makes the work day far more bearable. I've planned my route so I stay on roads with a 35 mph speed limit. So in Atlanta that means traffic is usually going around 70. I just take my lane, grit my teeth and keep an eye on my mirror.
After not riding for 10 years I got back on the bike and dropped 15lbs quick. Love riding, love my old bike.
