I was out in Phoenix a few weeks ago. The Flying J off of i10 has turned really sketchy over the past few years. They finally decided to do something about it ... 24 hr security inside and out. The guard outside circles the lot in a golf cart. They can tell the difference between expediters and others. No more homeless folks in the lot and no more sleeping in the driver's lounge. I stopped one of them to thank him personally. Staying overnight at that location was much improved.
Now if they would do something about all those bobtails ... lol
