It's not a dumb question. The entrance is NOT obvious. But Angela's directions are good. :)
Like Angela said, when you get to the "booth" stay to your left, it'll look like you're driving into the dump, but follow the path around, you'll see the parking lot around the bend.
Do what Angela Durham said...nothing more to be said
When you enter stay to your left...then follow the road to the back parking area.
