When you arrive on campus, you will park in the campus parking garage (Vulcan Parking Garage). If you enter campus on Third Street, you will turn right, just before the campus entrance in order to get to the garage (the parking garage is labelled NN on the map available under the Directions to Campus link, click on Campus Map & Visitor's Guide).
Most Conference activities, including registration will take place in Eberly Hall (labelled B on the map). The registration desk will be set up in the Eberly Hall entrance. When you register, if you drove to campus, you will be given a parking pass, which will be used to pay for your parking in the garage (you will use the pass to pay when you exit the garage).
