Reading all the advice that is being given in comments around this thread, it would seem the best advice would be: get someone who knows what they're talking about in the local area and get their advice; like the parent poster SAR but that also knows about dangers closer to home.
Maybe you could make a weekend of it for your families or something.
My SAR group actually teaches a class where one of our stated upfront goals is to prevent people from having to be rescued. Depending on the area, the local SAR group might be too busy putting out fires to do similar (it takes a lot of planning and prep).
