The last two shots were taken in the lower, enclosed, part of the observation deck. Amy, Katy and myself then headed up to the windy open-air deck above. After we had taken our pictures, Amy was ready to head down, but I asked her to stay up there for just a bit more.
It was on the (luckily leeward) west side, with me facing east — the direction of the rising sun — and Amy facing west — towards home — that I got down on one knee and asked her to marry me.
Through the tears of joy, she said yes.
