You won't believe what's at the bottom of Lake Washington

...planes, trains and highways.

What’s on the bottom of Lake Washington? Listener Merry McCreery wanted to know.

A couple of years ago, we went out on a boat captained by Mike Racine with five scuba divers to find out the answer.

It's an underwater museum, a place where you can’t go more than a few feet without discovering something. And the thing you’d discover out here, just off the boat launch, is big.

Really big.
