One vacation, staying at the Club Hotel Riu, I went out into the water {very murky in front of that Riu!} I dove, came up, then stepped on a black Sea Urchin! Ouch! A couple people helped me limp to the nurses station. Gosh, it really stung! Laid down on the table {wifey didn't want to pee on the stingers, like they say you're supposed to do ??}. The nurse proceeded to flick out the stingers with a long surgical needle {about 14 to 15 stingers in all} Couldn't walk on that foot for 2 to 3 days. This wasn't a major thing, like a broken leg or car accident, but it was my incident. I've had other self inflicted screw-ups...too embarrassing to mention. But, yeah, it is something to think about... What would happen if a person gets really hurt? But if it does, you just roll with it, and given the kind hearted dear Jamaican people & other people to help, we're in good hands ! Good Luck, be careful, use common sense, think ahead mon' Respect. This Negril.com forum is the coolest thing! Have ta go on it everyday!
