I have a harder time on right turns! I spent 1/2 hour a while back doing slow circles and figure eights in my street. Then on my driveway- it has some slope to it. I know my neighbor thought I was nuts. I work on getting the circumference tighter, even to the point where my knee is hitting my grip as I pedal and a need to tuck it in closer to the top tube. Yesterday I was at the park and did circles round and round the center of the basketball court, trying to stay inside the line. Working on these skills at home will transfer to the trail, and its fun too.
