Well, I finally went to the Coral Castle this past Saturday. It is easily one of the coolest things ever done by one of us humans. One tiny little (five-foot-nothing and a hundred lbs.) guy built the place, with only hand tools and no help. That means he quarried the stone in blocks of 2-30 tons each, carved them, moved them, and set them in place, all by himself. What he built will stand as long as there is ground beneath it. There have been some repairs made, and it's obvious to me, anyway, that the people that made the repairs do not have the skill of 'ole Ed. You've got to have one hell of a lot of skill to make a stone rocking chair that weighs a couple 'a tons, and works just as smoothly as any grandma could hope for. Not to mention the stone lazy-boy that damned near put me to sleep. My compatriot that day accused me of going to sleep, but I maintain that I was just really relaxed. :~) At least until she started kicking me ...

There's a gate there that weighs nine tons. It works just like any other revolving door, and just as easily. The bearings he used in it's construction worked for 60 years with no lubrication. When they finally gave out, it took six guys and a crane to repair what this one man had built. Now _that's_ cool.
And the cherry on the sundae is that he did it all because some chick dumped him.
Oh by the way, the place has a website.
