I heard both booms - they sounded just like sonic booms alright. I was sitting on the outside deck at Ray's Boathouse on Shilshole Bay with my wife. We enjoyed the rest of our meal, paid and went across the street to go over our wills with our estate planner. If the booms had been something more dire, I can't think of a better place to be than on the sun deck at Ray's. Or planning your will.
