Have you seen ALL the circles in DC, Little Hawk? Some are reasonable and simple (Chevy Chase Circle, Westmoreland Circle)...some are multi-lane, many-legged horrors that take months to learn...with inner and outer drives and traffic lights WITHIN the circle (Dupont Circle, Thomas Circle)...and some are just too much traffic trying to change lanes too fast. Very few are classic 'roundabouts'....none are 'fun', unless you think demolition derbies are fun.
