I made this trip a couple years ago in the Beetle.

I drove down the huge dirt road (Groom Lake Road?) as far as I could (clearly marked by signs, cameras, a security truck up on the hill, etc). I didn't get tailed anywhere, but they did keep an eye on me as I stepped out of the car and walked around and took pictures of the "Photography Prohibited" signs.

I'm sure that they have motion detectors along the 7 mile Groom Lake Road. The security truck was sitting on the top of a ridge as we rounded the corner. I doubt that he sits up there baking in the sun all day waiting for someone to drive up... they knew I was coming and they were ready, which is to be expected.

Not much to see, no UFOs or aliens flying around, but the Little AleInn was pretty cool. I stayed one night there, as I was on my way from Salt Lake City to Las Vegas, and I figured it would be a cool place to crash for the night.

It was a fun trip, I'll have to see if I can find the pictures.
