To work the south side (Vintage), just show up for class at the Ops Shack across the street from the Hangar Cafe, south of the Vintage hangar and red headquarters building. Classes used to be at 9am and 1pm but check on the time. Takes about an hour and you're qualified. To go to work just show up at the Ops Shack - there's no assigned shifts. You can work all day if you want. There's usually a 4 hour limit on riding scooters just so others can get a turn. But there's plenty of work to do without a scooter.
