Vanderbilt Hall bouldering wall directions:

The M2 shuttle that stops outside of Lamont Library will drop you off right
outside the building containing the wall- see the online schedule

Once you get to Vanderbilt, walk straight past the guard into the courtyard,
then walk around the courtyard to the farthest right corner. Go down the stairs,
take a left, walk through the basketball court to the far left corner. Walk down
those stairs, take a left, and the wall will be on your left. Sounds more
complicated than it is, just print out these direction and it will be obvious once
you get there.
