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

I read the RV reviews. Especially for RV parks on I-10 near El Paso. If they say that you need to keep a .45 by your bed, pass the park by. If they say that you need an AR-15 with a 100 round double-drum magazine by your bed... definitely don't patronize that place.

Usually the fact that an area is in a bad neighborhood pops up on the reviews, and unless there is an absolute reason to go to the area, it is wise to steer clear.
