Post offices in the northern state of Himachal Pradesh will take a customer's handwritten letter and computer scan it. Then the letter can be e-mailed to remote, high-altitude post-offices in this Himalayan region. From there, the e-mails are printed out and then taken by hand to their destinations - many of which are located in almost inaccessible mountain areas such as the Lahaul, Spiti, Kinnaur and Pangi valleys.
