Spiritual healer Dorina Rosin and her partner Maika Suneagle plan to have a "dolphin-assisted" water birth in the ocean, even though experts are warning that this poses many risks. For instance, there's the chance that a great white shark may show up. Also, dolphins in the wild aren't exactly the most docile creatures. They've been known to "toss, beat, and kill other mammals for no apparent reason despite enjoyment."
Nevertheless, Rosin and Suneagle feel these risks are worth it. After all, as long as they don't wind up dead, they believe their ocean-born baby will be able to speak dolphin. More info: CBS Atlanta
Also known as kite surfing Is a popular if dangerous sport. It combines surfing with getting blown around while flying a kite. The main problem with it, as far as I can see, is not so much the flying/surfing as it is the starting and stopping. Another place for Darwin-esque culling of the herd to take place.
I just finished reading this great book on cartoonist Virgil Partch, who defined cartoon weirdness for several decades.
The book revealed that Partch was a great joker in real life as well. He and some buddies founded the Balboa Island Sculling and Punting Society, which was an excuse to putter around the marina, freak out the squares and get drunk. Not satisfied with those activities however, they aimed higher. First they decided to take a "boat ride" from their West Coast hangout to Las Vegas. How? By putting a boat on a truck and riding inside the craft while being driven across the desert.
Then they decided to take a train to Catalina Island, by a similar expedient.
