Mr. aephi alum and I had spent the evening in Boston and were walking back across the Mass. Ave. bridge to Cambridge. Halfway across, I suddenly noticed he wasn't walking next to me any more. I turned around, and there he was, down on one knee. He put his class ring on my left ring finger and asked me to marry him. I accepted immediately!
It was semi-spur-of-the-moment. I think he wanted to plan something terribly elaborate and romantic and stuff, but he couldn't wait. It was still plenty romantic.
The Mass. Ave. bridge is marked off in Smoots, thanks to the LXA chapter at MIT. The bridge is 364.4 Smoots and one ear in length. The exact middle of the bridge is marked "Halfway to Hell", but Mr. aephi alum decided that wasn't exactly an appropriate label for a proposal spot

so he proposed at the 180 Smoot mark. So we will always be able to pick out the exact spot, and someday we'll be showing it to our kids and grandkids.
He also likes to say that he picked the spot because if I'd said no he could have tossed me in the Charles River.
