Hi Rhi,
So we can have the fun of digging up dinosaur bones and putting them together. Then putting them in museums and rearranging the bits we got wrong. And eventually make films about them.
Ah, that must be it then. Makes as much sense as any other answer I guess.
Incidentally, I was out your way (I think) for a cheeky 50 mile ride yesterday - Mountfitchet, Elsenham, Thaxted, Great Bardfield, Finchingfield, Wethersfield, Sible Hedignham, Beazley End, Stebbing, Great Dunmow, the Easters, Pledgdon Green and back. Absolutely stunning - you tell people you live in Essex and they think "Tilbury" or some such, but for my money we have chocolate box pretty villages and gorgeous countryside around here to rival any. Perhaps we should keep it to ourselves eh?
