I don't even trust some government! When our area was annexed several years ago, the town used their Zip Code in the address of our 'welcoming' letter. Apparently unbeknownst to the bureaucrats is that USPS service areas have very little to do with government boundaries.
All the letters were returned, of course. And, then, to add a bit of illegality to the event, the letters were placed in our mailboxes by town employees! I feel
so comfortable knowing we have such intelligent leaders...
Fortunately, since that time, we've voted most of that group out of office.
