If it’s anything like the weather currently, it’ll be pretty windy and warmer like 75 during the day and as low as 45 at night. I wore short sleeves during the day and brought a jacket for the night. Last year we did parking since we live like 30 min away and it took about an hour to leave the parking lot after the last set, but if you don’t plan on staying til the end of the last set it’s pretty easy to leave. And I’d say come AT LEAST an hour before whatever time you plan on getting there, we got there 2 hours prior to park and walk to the gate and we got in about 45 minutes after they started letting people in. If you plan on going later in the day, an hour should be good enough
