Unlike in the US, roads between towns are mostly extremely well signposted, even on country roadsGrab, you have obviously not tried travelling the country roads on Norfolk. I have on several occasions with my mother been a little lost and seen a signpost to a place that we know we can find our way back from. A mile or two down the road, you reach another road junction, well signposted except the place you were heading for has vanished from the signs (and no you are not in the place itself)...
Thinking of roadsigns, there is one outside our drive that I believe caused problems for a while. As far as I understand it, if you look at a map, the route from Norwich to Cromer is all in green (the trunk route) and the road from North Walsham is the red road. I believe the sign used to reflect that - the problem being that The North Walsham to Cromer road is all the A149 and the Norwich road (A140) stops and is the give way. Anyway, the signpost now shows it in a way that makes it clear - turn left for Cromer or right for North Walsham - mabe they changed it - I haven't heard of an accident there for a while (and it together with the last couple of bends coming from North Walsham have been the scene of several including fatal ones).
