I second that!!!

Lets not warn people where these check points are. The worst thing you can do for a drunk driver is to let them continue driving around drunk.

After they kill someone or hurt themselves then the will realize that they would have been better off getting caught by the police.. Because, guess what? if you hurt someone else.(or yourself) you're getting pinched for a DUI anyway.. So you may as well get pinched before you hurt somone.
