Hate to rain on your parade, but one of the reasons those traditional blue postal drop boxes are going away is mail theft. Too many of the older boxes have fallen victim to a pair of cutters or just a pry bar to "pop" them open. Even the newer reinforced boxes are falling prey to determined "desperate" thieves who are after ID data more than checks these days. To defend against this trend, the Post Office has been removing the boxes and encouraging people to drop mail off at actual post offices, preferably inside the post office.
