Snowplow Driver Took Out 30 Blocks Worth of Mailboxes

I'm sure snowplow drivers all over this country accidentally destroy a few mailboxes from time to time.  But this might be a record.

ABC 8 - Lincoln  reports that Lincoln, Nebraska got about seven inches of snow last weekend.  And now they're investigating how a plow driver took out 30 blocks worth of mailboxes on Sunday.  That's right:  Not 30 mailboxes, 30 BLOCKS OF MAILBOXES.

They say they'll have to cover the cost of the damage to all the mailboxes if they find the driver was negligent.  Why do I have a feeling they're going to determine he wasn't?
