Parking
Below is a map showing the Energy, Coast and Environment Building, located at S. Quad Drive (formerly Nicholson Extension) and Nicholson, next to the Credit Union and south of Tiger Stadium. Attendees should park in the "Event Parking" area. NOTE: If you park in the "Reserved" areas, your car will likely be towed.
After parking, enter the rotunda, register and pick up a parking pass (good for both days) to take directly back to your car and display prominently.
