HmMm..the tunnels were full of modern day stuff..VCRS, TVs and the ilk. some say its proof of secret soceities. then again others think its proof that there is another civilization beneath our feet. but whos to say they werent relics of some ancient tunnel system re-used for another purpose? its a mystery!

ooh and as far as having our past civilization's relics...could be linked the the whole Antlantis stuff. ever seen the postman? just because the old technology is there doesnt mean itll work again...
all in all i think were all throwing around some good ideas here follks
