Worked for me. There’s also drive-ins.com. The last time I checked, there were three theaters in the I-81 corridor of Virginia are still operating with one being near the intersection of 81 and 66.
The drive-in that my family frequented was the Starlite Drive-in on Route-17 in the Kankakee area. The very first movie I remember seeing was at that theater: a re-release of The Jungle Book. The last movie I ever saw at any drive-in was Star Wars at that same theater.
