Hard numbers are difficult to come by, but our hunch is that the police checkpoints intended to curb drunken driving this summer were a success. Word filtered out that even a couple of drinks could land someone behind bars for the night and result in fines or the loss of driving privileges for months, even on a first offense. This is good news for those who prefer safer roads, and it merits a tip of the hat for the many local officers, as well those from other departments, who put in long nights here to make this happen.
