I am what some cyclists call a Fred, in that I am just as likely to have bags and a rack as I ride to work or run errands. I have ridden many, many miles all around Atlanta. One summer I worked at Piedmont Hospital while living near Northlake. I rode to work every day, even down Peachtree from Peachtree Battle. I have become extremely sensitive to cars and traffic and everything that is on the road with me.
Trails are very nice.
They are good for beginners and those looking for some nice, easy exercise. To be a true commuter I need access to all roads. The problem stems from a lack of education and respect. And I mean this on both the automobile's part as well as the cyclist's. I have seen guys on bicycles run red lights and blow through intersections.
