How we relate, how we know what we think we know, how past mingles with present, how a bike stays upright, how the butt can bear that puny perch — a lot more than pedals and wheels goes around in Cycling in Plato's Cave. Just like a bike, the poems are simple but have deftly moving parts that roll us along, offer fresh perspectives, and let us feel the air. And just like on a sunny Sunday in June, or is it September, or maybe it's cloudy and broody outside, it's all about the ride.
