I noticed this location from a postcard in a souvenir shop in Boston while on a work trip. I managed to get to the First Church of Christian Science right before sunset and waited for the reflection pool to settle down. I was rewarded with a brilliant sunset and still reflection and was able to merge two exposures, one for building and sky, into this final picture.
