We spent some time at the Library of Congress on our DC trip back in December for Matt's dissertation. After you get through security (and get your official LOC research card!!) it was really just like any college library - and especially neat for a library-lover like me. Walking a mile in 40-degree rain didn't really add to the fun, but I'm glad I got to help my favorite grad student work.
