See you Monday at Herga. Easy to find, J18 of the M25, take the A404 to Rickmansworth, stay on it until it bends sharp right towards North Harrow; there you continue straight onto the A410, through Hatch End, and at the roundabout after the station turn right towards Morrisons. turn left into the Harrow Arts Centre car park. The room ("Weald") is at the End of the Road.
