I think there is a multi screen drive in still in our area, Kent. It's south of Seattle and I haven't made it down there in decades, but I thought it was still around. I live in Seattle and in the freaky Fremont district they used to show 50s-60s classic movies on the wall of a building and you bring your own lawn chair. They take over a parking lot. One of the better know media transvestites used to host the event and it was always entertaining. My wife and I saw Viva Las Vegas when we were dating a few years back. In Shelton, WA, the drive in there was struggling to make ends meet in the 80's and so they started showing pornos instead! But after a few years the neigbors got upset I guess and it's probably a strip (pun intended!) mall today.
