A long weekend still isn't that long, so Sunday saw us heading back down Watford locks in much cooler weather.  Still the sun did its trick again and came out in time for lunch at the New Inn at Buckby.  Then back through the tunnel, (accidentally breaking the cratch cover zip on the tunnel wall, not sure how), and a wait at the top lock for one of the following boats.  This turned out to be a training trip for one of the LNBP boats that takes parties of kids out through the year.  By the time we got to the bottom lock, it was clear that as well as the Spring, the gongoozling season was getting well under way.
