Picking the date from events in our lives, I chose the day I finally let her have my phone number. Lured out to DC under the pretense of taking family photos I tried to convince her to dress up. She wanted to know why and I couldn’t tell her. The end of that argument was obvious but the trick was not.
I chose the Netherlands Carillon in an attempt to distance the event from more obvious choices in DC. Some alternate choices were just too much trouble. We spent the rest of the day getting some pictures near those more obvious choices to use for later.
