Myth or fact: Giants of Solomon Islands

I'm much more into non-fiction than tall tales (pun intended), but this is too much to ignore.

Myth, legend — whatever you'd like to call it — there is one about giants in the South Pacific. An adventuresome writer named Jonathan Gray pens this story about the 15-foot original inhabitants of Guadalcanal and the Solomons.

There's much, much more to be read, but Gray's piece is just short enough to whet the appetite ... or completely disappoint. Me? I find it intriguing. Where did these legends come from? And why would so many people have so many first-hand accounts of encounters with these giants?
