So when I got home that night, I looked up the London Waterbus Company's website, and they were advertising these day trips. So very bravely I rang up to enquire, but got their answering-machine, and was very pleasantly surprised that they got back to me a couple of hours later to say that at the time they weren't sure whether the trip would go ahead, but they would get back to me a couple of weeks before the date to confirm. Which they duly did, and the tickets arrived in the post.
And yesterday was the big day. We were scheduled to leave from Camden Lock at 09:30, so for a more pleasant trip in the rush hour - although, as it is August the Tube wasn't too crowded anyway - we left from Brixton and changed at Euston. We weren't quite sure there was time to get coffee, so managed without.
The waterbus was called The Water Ouzel, and was a converted narrow-boat, with seats like an old-fashioned bus - not all that comfortable for a whole day! Fortunately it didn't rain, so the sides were rolled up and we could see plenty. The bodies of the 1950s and 1960s might have fitted comfortably four abreast, though, but those of the 2010s didn't, really, and there was much sucking-in of breath whenever anybody had to walk down the length of the boat to the loo at the back (they had lovely-smelling soap; I looked to see what it was but I don't think it was what it said on the tin, as that said it was tea-tree).
We set off down the Regent's Canal towards the Thames. The canal drops about 86 feet through a series of locks, and, thanks to a girl on a bicycle, we weren't held up at many of them. Mostly we shared the lock with another boat - a holiday let for the first part, then a narrow-boat that has been restored to its former glory called "Empress", and finally, towards the end of the day, the Tarporley.
After the first three sets of locks, we went past St Pancras and its eponymous lock, and then past King's Cross. Apparently the lines from King's Cross go under the canal, whereas the ones from St Pancras go over it. Then came the horrible Islington Tunnel, which was not pleasant, but I concentrated on looking at photos of my phone and we did, eventually, come out the other end.
Finally we turned left into the Hertford Union.
We were tired by then, and hungry, and decided to eat before we set off home. The local Wetherspoons was incredibly busy and incredibly noisy, but next door was a Japanese restaurant called Hi Sushi Salsa, which we chose. It was mostly sushi, which the Swan Whisperer doesn't really like, and although I like it, I have no idea how much to order for a main meal, so we both went with noodles. He ordered udon with seafood, which he said was lovely, and I ordered gyozi ramen. Which was also delicious, but I found the ramen and broth under-seasoned; unusually, it could have used more salt, and I would have liked a touch of chilli or Japanese ginger in it. The pork gyozi (pot-stickers to my American friends) were absolutely lovely, delicately seasoned and I wished there had been more! We then ordered ice-cream - at least, that's what I thought I'd ordered (the Swan Whisperer went for mint choc chip!), but it turned out to be ice-cream in some kind of skin, called mochi, which Wikipedia tells me is a kind of sticky rice cake. Delicious, but not quite what I was expecting! And Tiger beer to drink, which I don't think we've had since we were in Hong Kong over 30 years ago!
Then we really did head home, staying on the Northern Line all the way - and when we got off the Tube, the rain that had been promised to spoil our day had finally arrived! Luckily there was a P5 fairly soon, so we didn't get too wet, and we got in just after 9:00 pm. I was very, very tired!
