New to RV,when traveling how do you know what areas to avoid

Really cracks me up how much of a jerk some people are.. I spent 22 years as sheriff in Californa and was active military as well as Army reserve ..so yes I have insight and knowledge of reading signs of trouble, but what a crack up that you can't ask if there is some app or other ways available to help plan a long term trip in areas a person has never been in without some people making stupid remarks..
