You can escape the freezing winter snows and winds of Kabul by taking only a three-hour drive east through the Silk Gorge to Jalalabad, where oranges are being harvested. You can escape the humid summer heat in marshy Kunduz, where temperatures often exceed forty degrees Celsius, by moving to the mountains of Badakhshan.
