We had a very good experience at Lapworth earlier this year too. Sorted out a couple of boats in a muddle coming down, then accompanied us up, cycling ahead to have the next lock open as we arrived. Really sensible, assisting rather than taking charge, and good company too. Exemplary really. The guys on the Hanbury 3 are always good value too in my experience, although we've never actually had a bad experience. I think someone said before, perhaps they should have been named Lock Assistants since, when that's what they act as, that service is a real plus.
