Dulles Airport sign

This sign never fails to crack me up. It's on Little River Turnpike in Annandale, VA, just before Old Columbia Pike, directly opposite Osaka Restaurant.

It's funny because this is nowhere near Dulles Airport. The road it's on doesn't go to the airport. If you wanted to go to the airport, you probably would not take this road. I have no idea what this sign is doing there, and it makes me laugh.
