Over 40 years ago while driving back to college in a driving blizzard, my car stalled in the middle of the Walt Whitman bridge connecting NJ and Philadelphia, PA. The bridge police pushed me across the remainder of the bridge and around and under it !! - so far that I could not even see the lights of the toll booths through the driving snow. Totally unprepared with only street shoes and a light jacket, I nearly froze for an hour and a half. Fortunately the problem with the vehicle was a vapor locked carburator and it finaly restarted. I've always looked upon this serious experience as a blessing since I've never been so hopelessly unprepared since.
