I love covered bridges - probably got that from my mother who never drove/walked over a covered bridge she didn't like. As the family, and later Mom and Dad, traveled, if Mom even had a hint of a traveled bridge in the area, off she would go. She also was an avid photographer and every once in a while we run into one of her covered bridge pictures.
Yes, I think they are romantic. Anything outdoors, in a quiet picturesque setting is romantic. Definitely not if a bunch of site-seers are milling about.
