Yes, it still happens. What I've seen lately is SUV's with VERY DARK tinted windows approach the boxoffice with 2 persons in front and a bunch of blankets, lawn chairs, etc. thrown onto the rear seats. Well, underneath that "stuff" is usually 1, 2, or maybe even 3 more people hiding. When we catch 'em they are forced to buy tickets (that's our Skyline Drive In owner's policy). At our competition, the Rodeo Triple Drivein (35 miles north of us in Port Orchard, Wash), they take a hard line. Anyone sneaking in is thrown out ALONG WITH EVERYONE ELSE IN THE CAR WITHOUT REFUNDS and are banded from ever coming back. If they don't like it, then the nearby Kitsap County Sheriff will help them leave.
