I was out of town on a business trip and felt very isolated.  I did not know anyone and had no one to hang out with.

Oh, I'm sorry you had that experience. When I was traveling cross-country, I used to FaceTime or Skype friends and family. Would that work for you?

I could do that, but I do not like to go out to eat alone.  Skype does not help with that.

That's very true. Another thing I did was find a Trader Joe's or some sort of store and stock up on decent food. Eating alone's no fun, but at least you're safe and nourished!
