Have you ever spun a nine-ton coral rock gate with one finger? Do it on weed. Super-genius Ed Leedskalnin drilled a perfect eight-foot hole through an 18,000-pound block he moved by himself from Florida City to Homestead; then he centered and balanced it on an iron shaft and truck bearing just so you can spin it in circles. He built the castle as an undying tribute to the 16-year-old girl who dumped him the day before their wedding, and it's there for your enjoyment. Professional burnouts everywhere compare it to Stonehenge and the pyramids of Egypt. Ed worked day and night by himself for 28 years constructing it all using the powers of weight and leverage. He was five feet tall, weighed 100 pounds, and claimed he knew the secrets used to build the ancient pyramids and that you could learn them too. Button pushers, beware — items marked "Do Not Touch" are magnetically booby-trapped. You'll feel it later. Coral Castle is a world-famous mystery destination. See it yourself for $9.75, and group discounts are available. Bring your own weed.
