I would suggest that this checkpoint was a personal hastle of 99.8 % of the population. This number of citizens should be able to override whatever hold MADD has and change the names of the city council. Go for it guys.
My guess is that the degree of responsible drinkers is high and getting higher and MADD may be able to claim a victory here. But a checkpoint that nabs this small a number is a waste. No other name for it. The city should invest in a junker police car and leave it parked somewhere. It will do as much good for a lot less trouble and cost.
My pet peeve these days. I'm one of those people who "find" these things (checkpoints) on a regular basis.
I'm getting pretty sick of it, and BTW, don't ever ride with me.
They never get me for anything, but the delays are really too much annoyance-harassment, really.
