SLAS volunteers should plan to arrive around 7:00 be ready to go by 7:30 pm., on the Arch Main Entrance Plaza.  The crowd tends to diminish quickly, so you will get a lot more business if you come early.   Telescope viewing will continue until 10:00 pm or until the crowd is gone, whichever comes first.  No restrooms will be available after 8 pm, when the Visitor Center closes.   If you have a color printer, Rich can send you a parking placard that you can post on your dashboard.   This will allow you to park on the north side of Market St., just west of Memorial Dr., adjacent to the Plaza.  Otherwise, pick up a placard from Rich when you arrive.
