Yep, all by myself. Probably one of those things our mothers would warn us to never do! Never know where there's a hole in the ground to twist an ankle, or a snake waiting to bite... I went back behind the building (or buildings? I don't remember now) and there were a couple derelict trailers and vehicles back there. Another hazard is the various scattered debris to trip over, etc. This place had it all! Indeed, its very remote. Last I heard, some of old Rt. 66 is closed due to washouts and I think it includes this section. You can still go to Roy's in Amboy but no farther east than Cadiz depending on who you ask.
Troy Paiva has a good story about shooting at a place like this, and while walking around doing his lighting he felt a tug on his leg. Big spider web! Then when the photo was over, he looked down with his flashlight and there was a giant spider on him, its body as big around as his thumb! Of course, that could happen in daylight too but at night its even more creepy.
