The monthly hack night seemed to get a good response for the first Monday of the month, so we'll try again. This time, we're providing better directions.
Area 15 has a large grass parking lot near Davidson. Drive past this along one side of the building until you pass not only Area 15, but also a house on the Area 15 grounds. Take a left turn, followed by another immediate left turn into the primary Area 15 parking lot, then park. You will see a set of stairs there. Take them, walk in the white double doors (which will be unlocked). Follow the flow of the building forward and to your left, and you will see the hacking area!
