Postboxes not evenly distributed

Though the number of people using the postal system has reduced, there are some people who continue to use the postal system for communicating especially as theft of emails, smses and diversion of phone calls has increased. However the post boxes are not evenly distributed, in the city centre of panaji, there are post boxes at almost every crossing, while elsewhere in the suburbs there are no post boxes for kilometers.
So people who wish to post a letter in the suburbs have to waste a lot of time searching for a postbox or wait till their next visit to the city to mail their letters.
