Six and a half hours to travel 200 miles from Liskeard to Berks. Arrived at Exeter the instant a lorry hit a barrier above Junction 29, paralysing the whole of the farther West of England. A friendly caravanist advised us to stay the night. Impossible. To get back home meant a journey via Tavistock with all the other divertees over roads not wide enough for a decent sized horse. Infrastructure? It’s a laugh.
