Obviously try to keep the sign, it should be a non topic. Yea its just a fucking sign, its also the most recognizable part of Boston for some reason. Its interesting, its been here for a long time, its unusual, its Boston. Weird things like this make cities unique and interesting. When I was stationed in NC I would go to Raleigh and see the perfect roads, perfectly uniform concrete sidewalks, a stale as hell Tampa low rise excuse of a skyline, no brick, no limestone, no terra cotta, nothing interesting, nothing unique, just vanilla ice cream with a plain cone. Boring. Quirky things should be embraced. Knock down some "insignificant" old brick buildings here, put pavers on all new development there, and the next thing you know you slowly erode a lot of character.
