Steam Leviathans

We're going on holiday to Somerset in September. Here's a visitor attraction I'd love to see, time and toddler permitting - Isambard Kingdom Brunel's pioneering iron-hulled steamship, the SS Great Britain. It's a great pity that his later design, the ill-starred but awesome Great Eastern didn't survive into the 21st (or even 20th) Century - that really would be a sight to behold.
