Breaking and Entering! Police called to Violent Narrowboater!

We almost get halted as a narrowboater tries breaking and entering a damaged lock, then get's violent, resulting in the Police being called at Kings Langley! After the faff, we drop by Waterways Experiences on the Grand Union Canal to check out their disabled accessible boats and talk to some of the volunteers. Colin discovers the story of the Ovaltine factory, the local paper mills, and why there's a Lock 69A on the way to Hemel Hempstead.
