It is interesting to me how far apart in time some of these were. It must have been quite an experience for it to stay in the minds of revelers for so many years between them. Or perhaps it it one of those things where it dropped out of though for sometimes decades at a time, but the Thames was such a large presence in their lives that when it froze over stories from parents/grandparents came flooding back and they wanted to recreate and have their memory of standing in the middle of it?
