Today's Geo Quiz was inspired when Jake Shimabukuro stopped by our studios.

Jake Shimabukuro

Jake is known for his lightning-fast fingers and clever arrangements on the Ukulele.

"Where was your uke made? This ukulele is a Kamaka, it's a 4 string tenor ukulele, its all Koa wood and it was all handcrafted ...What kind of wood? Koa? Its Koa it looks like a tiger pattern, which is why they refer to it as curly koa."

Koa tree

Curly Koa, or Acacia Koa --- that's the clue for today's Quiz.

Koa is a species of tree endemic to only a few Pacific islands .. its reddish wood has been used for dugout canoes, ukuleles, even fancy surfboards.

So we want you to tell us where Jake's uke comes from...and for EXTRA CREDIT -- where do ukuleles come from?
