Yes, it's another round of that classic guessing game - Animal, Vegetable, Mineral, Abstract [or any combination thereof]. This effort - '03/'04 should address any queries, but then again, may just serve to confuse and baffle which some might say is the point of the game. Patience, integrity and a decent search engine may be useful ....
(Raak) Not really architecture. (ISP) Not Stonehenge or a man with a huge willy. (Lib) NO, and I'D SAY YES :-) (Projoy) On the coast? Not really ON it so much as . . .
(Projoy 1) Not the coast itself. (Lib) Not the White Cliffs. (Projoy 2) Not The Coast anywhere. (irach) Not the Sands of Dee. (Irouléguy) Not the ~Jurassic coast.
You have all wandered into the outer regions of darkness where it is very cold. Look at the answer to Lib's second question. This is man-made.
Projoy - YES, made of stone. Raak - Not a sea defence. Inkspot - YES, connected with transport *audience cheers* ISP - Not the Chunnel, but *HUGE audience cheers* Lib - Certainly is in one direction, maybe two.
Lib1 - Half of it UK lurker - YES Chalky - Not the Blackwall Tunnel Lib2 - Would I put up anything as arcane as that? 828 yds, BTW :-) ISP - Not part of the tube.
But we have a winner, and it's RAAK, with the Severn Tunnel. Your go.
[Chalky] Not at all complicated. Just an ABSTRACT ANIMAL that I expect everyone has heard of. [Rosie] Yes: the unhelpfully distantly related mineral thingummy is a physical structure.
I confess - I've never read the book... made an assumption based on chess that if there's a white knight, the should be a black knight. I suppose you're going to tell me it's red instead! :-)
Technically, there are four knights, and the white one Alice meets, according to Carroll's detailed schema for the book, is the White King's knight. The other Knight is the Unicorn. On the red side, the Red Knight that the White Knight fights is also the King's knight, with the Carpenter as the Queen's Knight. (The Walrus is the Red Queen's bishop and the Lion is the Red King's rook).
[Projoy] It is indeed The White Knight, and you have correctly identified the tenuous and unhelpful connection with water-traversing constructions. [UK] You must read it, and Alice in Wonderland forthwith!
