Gate volunteers make sure that every participant has a ticket, and every car has a parking pass, in order for either to enter the event. You'll be checking IDs against a list of valid tickets and passes, and giving wrist bands to people on the list. While you will be talking to humans, that doesn't mean you have to be part of the Sunshine Squad-- people going through Gate, while friendly, are usually focused on getting into the burn, so goal-focused burners should feel comfortable signing up for this role. The ticket and pass lists may be kept on a computer, but if you're uncomfortable with using it, there will likely be another volunteer who is willing to be in charge of the list.
Gate volunteers meet for their shift near the front of the property, in the open space between Mama and Papa Zen's house and the nearby barn. You'll see it when you arrive at Constellation-- you know the place where someone checked your ticket on the way in? That's Gate.
Depending on how many people are entering the burn while you're there, there's a good chance you'll be on your feet for a lot of your shift, so wear comfortable shoes. Gate usually has pretty good tree cover, and will likely have a pavilion for extra rain and sun protection. That being said, bring sunscreen and/or other appropriate protective gear to take care of yourself while on your shift.
Good to bring: comfy shoes, water, and protection from the sun (eg. sunscreen, umbrella, etc).
