As I've said, we like to ride our bikes in the area northeast of Harpenden. Here are photos taken during some of these rides.

This is Shaw's Corner, George Bernard Shaw's country home, Shaw's Corner, now owned by the National Trust and open to the public, though it was closed for the day by the time I rode by.

A day hiker has plenty of paths to choose from. Here's one of them:

The rural lines are mostly one-car wide. This truck stopped traffic while it unloaded sheep.
