To say that Peter Monro is interested in paths and path design is an understatement. The Portland, Maine, landscape architect has designed paths and networks of paths and now has launched an authoritative blog——about the “principles and particulars” of walkways. His goal is to promote better design of walking paths. The observations and recommendations on his website are based on years of research, practice, walking and hiking, and even some inspiration from a talk he heard, while he was a Conway student, on how garden slugs navigate. Writing of Rousham, a small farm estate north of Oxford, England, designed by William Kent in the 1740s, Peter states,  “It was as though here at Rousham William Kent offered proof that he understood the very fundamentals of human nature, the kinds of places we humans seek out for protection and comfort, the kinds of routes we want to take.”
