Biking for Natural History

Although the typical means of enjoying nature would be by walking, I have found that biking can be a great way to find natural wonders in any area which has biking trails.  The rails to trails paths are ideal since they tend to be easy to ride while watching the passing nature show.  One of our favorites is the New River Trail State Park in VA which has repaid repeated rides on the same trail segment to spot daily and seasonal changes in natural history.
