Feb 21 2015 approx 10 PM to midnight. License check but also asking where your coming from/going to and if you had anything to drink. A “yes” answer obliges you to pull over and perform a round of “stupid human tricks” a.k.a. field sobriety test. Pass those and they let you go. Fail and you get the breathalyzer test and might even win a trip to the county hotel. From what I hear this is a fairly common site for the roadblocks but first time I have seen it.
