You may park in any unmarked space on any of the streets on campus. After parking walk northward on the sidewalk that begins where the red dot is in the center of the map above. It's across the street from the flag at the corner of Williams Street and River Avenue, immediately adjacent to a building that says 2221 Williams on it. When you get to Viola's Closet (just before the basketball court), take a right, and then your first left. The entrance to the Valley Room is a few feet ahead on your left.
