Police are planning checkpoints for three Saturday nights this month to nab drunken drivers.

But officers have one surprise in store for intoxicated drivers - they won't say for sure where the roadblocks will be erected.The checkpoints, Oct. 15, 22 and 29, will be in effect during the evening and early morning hours, Chief Dennis Nordfelt said.

The locations may be set up on 35th South from 12th West to 70th West; 56th West from 23rd South to 42nd South; 32nd West from the frontage road at 21st South to 43rd South; and Redwood Road from 24th South to 40th South.
