Berkley White of Backscatter just had two spots open up in his upcoming oceanic white tip shark expedition to the Bahamas this coming June 15-25, 2008.
I'm typing this message from the Shear Water at this very moment; we have just returned from a successful white tip expedition and had sharks literally from the moment we arrived after more than 30 hours of motoring!
