Looking and Seeing

According to Danny Udall of Eastern Moors Partnership talking about path erosion,
"All users cause erosion both walkers and mountain bikers"

In two years mountain bikes were responsible for turning this - A Fine Path - in 2009, into this - Faller. in 2011.

Apparently, "Mountain bikers do a great job of getting involved in that programme of maintenance making there use sustainable (sic)."
