Off to monmouth area next weekend 14th for a family party.
Taking the Drz's on the trailer, recommend a route please

BC it's not a part of the county that I would associate with green laning bearing in mind it's not something I do myself, perhaps someone else may know different though. Taff's brother is on the Gwentpol M/cycle section try pm'ing Taff and he could put you in touch with him.
