Hertingfordbury Roundabout - On either turn off, off of the A414 dual carriageway. Both are used during the day midweek, and evenings every day. Coming from Hatfield going towards Hertford either - 1. Take the first exit, left, which begins to go up hill and goes to Tewin and Sele Farm. Turn immediatly left off of the round about on to a track that leads into an open car park and head to the end. This location is used mostly midweek during the day. 2. Take the third exit, right, going into Hertingfordbury and turn immediately left into a dead end road with a brick wall running along side. The white house is empty and the short road does not go anywhere. This location is mostly used in the evenings.
