Spent the weekend out at the coast with a group of aviator friends at the only beach state airport in the lower 48, Copalis State Airport at Copalis Beach, WA. The sand is rock hard at low tide and I think you could have landed a 747 out there. The airport normally has about 220 aircraft operations per year. We landed over 54 aircraft on Saturday from all over the Pacific Northwest, hung out for several hours and departed without leaving any trace of our having been there. The weather was perfect with about 15 knots of wind straight out of the north making for a rather epic day at the beach.
