oops, misread the premise. big difference between "want" and "need." The particulars of the situation would further dictate my course of action.

Have I lost contact with loved ones? Cell phones down? No service?

Simply wanting to get home doesn't mean I have to get home. Without an urgent need to get home ASAP I'd probably take a detour, look for alternate routes, or hunker down where I am until the road is clear.
