Another one:
After the above incident, the oppressive government tore down the rickety bridge. A new bridge was built at a wider point of the chasm. This bridge has a guard house halfway across. The armed guard comes out every three minutes and make sure no one is crossing the bridge in either direction. This bridge takes four minutes to cross. The bridge was built with smooth edges so there are no handholds and the hut is positioned so one cannot hide behind it. How do you flee the country now?
EDIT: This puzzle is just you (or some other anonymous person), not the family in the above puzzle. They're already gone. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
