@LovesTha@mansr the lots squeeze together in the front on this part of street. Some mailboxes are on opposite sides of a driveway, and others are ~120ish meters apart. Was trying to give a rough average.
Where my parents live, the mailboxes are all together in a little cul-de-sac and so the post office truck just has one stop in that part of the neighborhood. As I understand it, all the new neighborhoods have to do that with their mailboxes now - the USPS seems to want to phase out mailboxes at each house to make delivery faster and more efficient.
