Had a couple of hours spare in Cumbernauld on Monday night waiting for the kids so rode round on the bike.
Main parts added to map are the Eastfield Road roundabouts and Balloch Loop Road.

The results from the road sign photos at night are great. Wait for no traffic (don't want to distract anyone), roadsign reflects flash and gives very clear image. Tried photos of a couple of junctions to remind myself. Waste of time, almost total darkness.
