The man is Danny, and his Dog is Two Keys. I don't know the other man's name. Yes, Danny and Two Keys sometimes sit at the Valero, but I've never had Danny solicit me for money. I've given him money and coffee, but he's never asked me for anything, or said anything to me other than thank you and bless you.
I believe they do make their home somewhere in the wooded area near the Salado Creek bed, but I don't know where. I must say, I don't worry about them a bit.
As far as their cutting trails that others can use, I doubt it. They're very low-key, and I don't think they want to draw attention to themselves.
I worry more about some of my neighbors than I do about Danny and his dog.
