    Re: Dependence on GPS

    Yes typos and all!  In fact just yesterday this iPhone GPS got me in
    trouble (ok it was operator error). I typed in an address for the
    visual arts college in St Paul mn. It seems there is a divider for
    this street (E/W)... So my wife and I walked the 1.3 miles to find no
    college. I figured out the mistake and we walked the 1.4 miles to the
    proper place, 0.6 miles from our original locaction. My wife has been
    quite generous telling all about my navigation prowess!
