Axo and Help-- I'm glad you both put down some realistic comments for this guy, and others, to be aware of--especially the narrow busy road aspect.
Axo--I've read of similar sustran cowpath offerings that sound like a real pain in the keester.
Your experiences of more north very much mirror my northern Scotland experiences of things being better off, although to be fair there are always narrow roads and some pretty damn busy.
Re being on the other side of the road, I was surprised how well I adapted. Touch wood though at all times for some busy intersections.
Again, pertinent points you both brought up.
