Picture from Good Hank‘s flickr photostream. This is #5 of 12 planned metric centuries (one each month) for Good Hank and pals. Click ‘more’ to see how they spent the night on this trip in the Peak District National Park in Derbyshire, England. BTW, the rock formations on the right are gritstone tors which have been formed by wind, rain, and frost over many centuries.
Good Hank is documenting the monthly metric centuries and other cycling exploits, you can read those here.
