I never saw a dino at the British Museum , it is full of human history. Congs would arrange visits & there was a group of pioneers who (I think counted their time) and took parties round .. The museum descriptions say that Jerusalem fell in 587 BCE , the guide said 607 BCE . I totally believed our guide and marvelled how "the world" could be so wrong so often......
I went on those tours a few times when I was young. I used to be really excited about going... because there was an amazing comic book shop over the road from the museum entrance. Actually, now I come to think about it, going to Cardiff Assembly was exciting because there was a Forbidden Planet comic store just round the corner from the stadium! Since leaving the JW's I haven't been in a Comic book store, but there's the internet and Amazon now of course!
