It has to be said that Norfolk CC aren't the greatest at signage. Drove an incorrectly signed byway last night (dark evenings + first night laning :D ). It is signed at one end as 'Public Bridleway'. Despite recognising the error, it has never been corrected.
Suffolk CC, on the other hand, are excellent. Regular maitenance, well signposted, helpful RoW department, etc. There are many councils who would do well to follow their lead.
