I don't have the childhood memories many of you have, growing up in and around the park. I wish I did, but time and distance mean that I've only been twice - once when I was 8, and then again when I was 26.
However, I have this incredibly strong memory of riding in the Subs with my parents. I don't think everybody got in, claiming claustrophobia, by I have this distinct memory of lining up along the docks and the sensation of going "underwater". As the years have gone by, I know exactly how it was all done - including the fact that we never actually submerged - but nothing will convince me (especially given that they are no longer there to contradict me) that I wasn't genuinely 20,000 leagues under the sea.
Thankfully, this is coming back in some form or another next year.
