Parking is free on Thurday night (after 5:00pm), Friday night (after 5:00pm), and all day on Saturday in all the parking lots. The closest to the conference site is parking Lot E.
For Friday before 5:00pm, you can park in Lot N (Visitor space) at the north end of the campus, close to the Neuroscience building (CCBN). There is a permit dispenser located there which accepts coin or credit card or you may pay for parking on your smart phone using the free app called Honk Mobile. It is a one time registration and then you are ready to go.
Cost for a full day parking is $10.00 and if you do not need the full day you can pay for the portion you need.
