Take I-40 to I-49 North (exit 12).
Enter through the main entrance to the Engineering Research Center (the glass doors
near the flag poles). Check in at the front desk. Go through the doorway to the
left of the reception desk, then turn right and continue down a long hallway. Turn
left at the next to last halway (watch for CTTP signs). Finally, continue down that
long hallway and our classroom is on the left.
